Changes for Next Edition p.82, Sample Exercise 2.18 Moles Ba3(PO4)2 = 1/3... Grams Ba3(PO4)2 = 1/3... p.87, 2.70 This question reinforces a bad idea that getting the students to abandon is one of our principal goals in physical chemistry. p. 119, 3.99(a) Should lose the pink and blue background in the figure‐ it is not physically meaningful. p.182, q. 4.11 This is a nice open ended question‐ would be good to trace both all the way back to nuclear reactions in the sun  *p. 185, q. 4.49, SO2 should be 2SO2 p.186, q. 4.74 The text of the question refers to ‘Exercise 4.8’, whereas the answer refers to exercise 4.59. *p.188, q. 4.108, Nitroethane formula should be C2H5NO2. *p.188, q.4.111, 55 × 1016 should be 5.5 × 1016. *p.228, q. 5.73 Should this be Gibbs Free Energy, rather than enthalpy? pp.242‐244 I don’t think the concept of a positive electron affinity, as outlined in the text, is valid based on how electrons ought to behave... I think it would be much better to just put ~0 instead of >0 in Figure 6.9 and omit all mention of positive electron affinities in the text and also in questions 6.38‐6.40, 6.71, and 6.74. p.270, Sample exercise 7.5(b) ‘1.80 D’ in the equation at the top of the page is wrong; should be ‘1.08 D’. p.289, q.717 Replace Se3+ with Sc3+. pp. 334‐335 In questions 8.55, 8.69, and 8.70, I have gone through considerable contortions trying to interpret the experimental evidence in terms of the VSEPR model, it might be better just to leave out my changes and apply the same interpretation of the VSEPR model throughout even if it gives erroneous results. In the next edition it would be advisable to change the questions so that the example are cases where predictions of the model are consistent with theory and can be interpreted in a consistent way. p.365, Table 9.2. The factor ’10‐2’ in the table is confusing to students. Like I said before: ‘The ‘×
10-2’ in the table heading confuses many of my students. Might it be better to give the a
values in the Table in L2.kPa.mol-2, that is: He 3.46, Ne 21.4, etc.’ p.368, q. 9.4 Background shading colour should be removed. p.393, Figure 10.25. Questions 10.40 and 10.41 are difficult to answer quantitatively because the scale on this figure is not linear. It would be good to label the axes with logarithmic scales to enable interpolation, which probably means the figure should be larger. p.444, q. 11.31, 11.32 Temperatures should be specified for these since they rely on knowing a density for water. p.486, q.12.9 The ‘orange’ spheres seem to be red. To me, anyway! p.522, q. 13.7 Refers to (1) and (2) in the question and (a) and (b) in the figure... should be harmonised. p. 564 – Exercise 14 answers. It would be good to put names of compounds in the answers to get students used to them‐ e.g., talk about ‘calcium oxide’ on occasion, instead of just CaO. p.601 ‐ cut question 15.2 c; it is subject to manipulation by pedants such as myself. (i.e., you could get there by adding a very dilute solution of strong acid or base, since the bars are in terms of concentrations). p.603, question 15.23. 355 ml is the volume of a US softdrink can. In this wide brown thirsty land, it should be 375 ml. p.605, question 15.56 b. This cannot actually be answered from Figure 15.18‐ replace with an easier question? p. 605, questions 15.63‐15.68 These questions would be easier to answer using the expression pH = pKa + log(b/a), worked answers using the Henderson‐Hasselbalch equation would be good next time. p.606, question 15.72 We need to assume that the lake is quite basic. p.606, question 15.78, change to 23.7 mL of NaOH solution. This will make the calculated answers fit butanoic very nicely. p.647, question 16.34. Should state whether it should be answered in acidic or basic solution, since there are several reactions with oxygen as the oxidant in Appendix E. p. 647, questions 16.36‐16.40. I don’t like expression 16.11; it is very much a ‘put in the numbers and turn the handle’ sort of expression that will lead people to make mistakes at temperatures other than 25°C, and a holdover from the days of slide rules and log tables when people didn’t have ‘ln’ buttons on their calculators. p.648, question 16.50. Should change cell emf to +0.09, to give a more reasonable Ksp in the final section. p.667 Explicitly include the reaction of alkali metal peroxides and superoxides to form hydrogen peroxide, if they are going to be in the answers‐ I have changed the answers to treat H2O2 as a short‐
lived intermediate. p.671 Table 17.6. Add CN– to list at oxidation state –3. p.689, question 17.2. Better to make black atom blue, and say ‘a’ chemical reaction rather than ‘the’ chemical reaction. Since could be PH3 or CH3– plus water, for instance. p.689, question 17.4 – Should refer to equation 17.31 p.692, question 17.35(c) – reactions of peroxides not given in book, except for H2O2. Chapter 18: Introduce terms ‘facial’ and ‘meridional’ for naming isomers? p.699, Figure 18.4 ‘Zn’ and all data pertaining to it are strangely fluorescent green instead of black. P.729, remove ferrous and ferric for Fe2+ and Fe3+. *p.730, question 18.29(d) This question has been bollixed up and now makes no sense. It should be [Ni(CN)5H2O]3‐ Hydrogen peroxide has not been mentioned as a ligand and in light of this and the previous version of the question , 18.29(b) should be K2[MoOCl4H2O]. p.730, 18.30(f) Should be [Cu(bipy)2IH2O]I (to get rid of the last coordination number = 5 answer.) p.730, question 18.34 ‘The coordination number of the complexes is either 4 or 6.’ Should be given in the question. p.763, question 19.41 (a) Should state explicitly that 11.996708 is 12.000000000 – mass of 6 electrons. p.764, question 19.56 ’21.31’ should be ’19.31’ question 19.57, ‘3.2 = 108’ should be ‘3.2 × 108’ p.778, Figure 20.8 Still don’t like this Figure‐ there are much, much more beautiful ones illustrating the same effect out there! p.780, ‘Methane as a Greenhouse Gas’ Suggest adding somewhere: ‘Kangaroos are not ruminants and do not emit methane. They are also very tasty!’ p.791, question 20.33 ‘is found in most detergents’ would be better ‘is found in many detergents’. 20.46: put dot on OH radical: ‘OH•’ (?) p.792, question 20.61 Add final line to question: ‘How many days did it take for the oil spill to decrease to 10% of its initial value?’ p.793, question 20.64. Should give initial pH of the water used. Throughout the organic section answers, there is a hodgepodge of illustration formats‐ some line drawings, some jpgs for chemical structures‐ this should be made consistent and pretty. p.824, question 21.58 should be ‘less than or equal to C6H14’ p.847, question 22.19(d) should be ‘ecstasy’ Chapter 18 vs. 22: Wasteful duplication of material on isomerism in coordination complexes. p.861, Figure 23.17 Just reiterating from when I read this before, I hates these false colour electron micrographs with a vengeance, I does. p.879, Table 23.4 The ‘mPa’ should be ‘MPa’. Mega, not milli; these polymers do not fall apart in a gentle breeze. p.885, question 23.11 Specify that structures must not be cyclic. Chapter 24‐26: There are still a tremendous number of aromatic examples in the questions, with an expectation that the students will be familiar with things like toluene and benzaldehyde, while aromatics are not formally considered until Chapter 27. This really needs to be fixed for next time. Perhaps a whirlwind ‘overview of functional groups’ should be incorporated in Chapter 22, replacing duplicated material on inorganic stereochemistry and small amounts of intro from chapters 23‐28 that will no longer be necessary. Question 26.36, for instance, is particularly cruel... p.906, Concept Check Question. This question requires the student to know that alkly halides can undergo substitution or elimination reactions, but appears immediately *before* the introduction of elimination reactions. It should be moved to p.907. *p.919, question 24.4(i). Structure CH3OH2CH3 makes no sense. Replace with CH3OCH3, the CH3HO that was there in the last edition, or something else that does make sense! p.922, 24.41. Should alcohol functional group take priority in naming? i.e., 3‐methylcyclo‐3‐
hexenol? 24.48 Delete: ‘What this means is that when one equivalent of water is added, only a 50% yield of the alcohol is likely’. ‐‐‐ since yield will depend on position of the equilibrium. p.923, 24.53 Replace ‘‐CH3’ with CH3+ to match answer. p.924, 24.78 (c) Change to: ‘Predict the two most likely mechanisms (substitution and elimination) for the reaction of 2‐iodohexane with sodium ethoxide and give the products of these reactions.’ pp.924‐925, ‘Multistep synthesis’ – a nice way to tie the chapter together would be to add to each question: ‘Indicate the mechanism of the reaction that occurs at each step‐ e.g., SN1, E2, addition...’ p.955, Concept Check 25.9 This is just regurgitating information from page 954 ‐ should think about a different question. p.959, q. 25.11 Following: ‘Which of the following reducing agents is best used in the reaction shown below?’ – no reducing agents are listed. This should be remedied. p.961, q. 25.21 (a) Is not a reaction of an aldehydes or ketone, though it is the first reaction listed under ‘reactions of aldehydes and ketones’. Replace or move? p.971 In discussing formation of carboxylic acids at benzylic carbon, should specify that secondary and tertiary benzylic carbons preferentially undergo cleavage to form carboxylic acids, rather than ketones and tertiary alcohols respectively, under this treatment‐ this is necessary for answering questions 27.56 and 27.57. p.962, 25.33. First part is not very clear. Second part refers to functional groups and reactivities introduced in Chapter 26. Suggest deletion of question. p.983, Figure 26.14. There is still a non‐physical void in the centre of the micelle picture – the hydrophobes in the micelle should be shown as overlapping to get rid of this. p.999, q.26.18 (c). This is a carboxylic acid, and the question asks: ‘Classify the following compounds as acetals, alcohols, hemi‐acetals, esters, or ethers:’ – so should add carboxylic acids to the list. p.1001, q. 26.36 This question should be moved to chapter 27, as the answer starts with aromatic substitution not yet considered in this version. p.1025, first scheme. Captions are all wrong, the initial compound is clearly nitrobenzene as stated in the text, but it and all its derivatives are named as toluene. p.1029, q. 27.20 (a). ‘Draw a benzylic cation.’ instead of ‘Draw a benzylic cation?’ p.1030, q.27.39 ‘Draw all the resonance structures of the species shown below.’ p.1049, Figure 28.15  should be Figure 28.13. The figure numbers after this for the rest of the chapter are also confused. 28.16 to 28.19 should be 28.14 to 28.17, and 28.21 to 28.37 should be 28.18 to 28.34. p.1077, q.28.13 (b) ‘What accounts for the difference in boiling points?’ is not a good question, since no boiling points are given. Better to say: ‘How would you expect the boiling points of these three amines to vary, and why?’ p.1079, q.28.42 Should change the colours or label the spots for the benefit of the red‐green colour blind. p.1081, question 28.66(a) – ‘amide bonds’ should be ‘amide groups’ or ‘peptide bonds’; ‘page 1062’ should be ‘page 1067’. p.1082, question 28.75. Penultimate ‘T’ in mRNA sequence ought to be ‘U’ – there is no thymine in RNA. p.1088, concept check 29.2. It should be specified that the molar extinction coefficients given are for visible light. p.1096 Before: ‘any atomic nucleus that has an odd mass number, an odd atomic number, or both, also has a nuclear spin and resulting nuclear magnetic moment’ After: ‘any atomic nucleus that has an odd number of protons or an odd number of electrons will have a non‐zero nuclear spin and resulting nuclear magnetic moment’ Questions 28.82‐83. How the purine and pyrimidine rings are numbered should be given in the text somewhere. p.1134, question 29.56 It would be good to be able to say what fragment gives rise to the very big peak at m/z = 114, but I haven’t figured it out yet :/ Appendix C The error between the two ΔG values in question 4.87(c) comes from using thermodynamic data from two different sources in the table. I recommend for P4O10 using the following values from the CRC Handbook: ΔH= ‐2984.0 ; ΔG= ‐2697.8 ; S = 228.9
