Electronegativity and Polar Bonds Ch 12 What are the types of bonds we know of? Remember the concept of electronegativity…. Let’s look at hydrogen gas…. Let’s look at hydrofluoric acid…. Are electrons shared equally? Bond polarity‐ Nonpolar covalent bond‐ Ex. Polar covalent bond‐ Ex. Dipole moment‐ Using electronegativity values, arrange the following bond in order of increasing polarity. H‐H O‐H Cl‐H S‐H F‐H For each of the following, choose the bond that will be more polar. 1. H‐P H‐ C 2. O‐F O‐I 3. N‐O S‐O 4. N‐H Si‐H Arrange the bonds in each of the following sets in order of increasing polarity: 1. C‐F O‐F Be‐F 2. O‐Cl S‐Br C‐P
