So, does the type of bonding in a compound affect its properties?
LET’S FIND OUT!
Pg. 269 of the Red Chemistry textbook
1.
Differences in properties are a result of what?
2.
For covalent compounds, where are the bonds strong and where are they relatively weak?
Strong:
Weak:
3.
What are the weak attraction forces known as? Two different names!
4.
Fill-in the following table about the different intermolecular forces:
Where are they found?
Strength?
Dispersion
Force
Dipole-Dipole
Hydrogen Bond
5.
On pg. 270 now, the properties of covalent molecular compounds are related to what?
Ø What do these forces result in?
Ø These forces also explain why many molecular substances do what at room temperature?
6.
If a covalent molecule is a solid, describe what it would be like and give an example of it.
7.
Some solids, called covalent network solids, are what? Also, give 2 examples and list
the properties of these covalent network solids.
Ø From Figure 8.25, why are network solids used in cutting tools?
HOW IT WORKS!
Gecko Grips!
Pg. 271 of the Red Chemistry textbook
1.
Describe a gecko toe.
2.
What are setae? And, what does a vast number of spatulae provide each seta?
Setae:
3.
Spatulae provide…
So…tell me why a gecko sticks! A little detail here please!!!
WHY DOES A GECKO STICK???
4.
And finally, how does a gecko let go? Why does this work?
HOW DOES IT LET GO? WHY DOES THIS WORK?
