Which of the following has the highest pKa?
  a. HClO4
  b. H2SO4
  c. HNO3
  d. HF
  e. HBr



Question 2

Explain why (using resonance structures):
 

Question 3

Draw and label an energy level diagram for the MOs of
 

Question 4

Discuss the relative energy and contribution made by each resonance structure below. Include factors
  such as electronegativity or inductive electron donating groups, number of bonds and charges, and
  complete octets.


 

Question 5

Which is a stronger bond, sigma () or pi ()? How does this difference affect the relative reactivity of
  compounds with  bonds?

Answer to Question 1

d

Answer to Question 2

Although there are two resonance structures for I, there are three resonance structures for II and one
of these has all filled octets.




Answer to Question 3



Answer to Question 4

Contribution: II > I or III. I has the positive charge on a carbon next to two electron donating carbon
groups and one oxygen. II has the positive charge on oxygen which is electronegative, but it does have all
complete octets. III has the positive charge on a carbon with only one electron donating carbon group.



Answer to Question 5

ANS: Since  bonds are stronger than  bonds, compounds that contain  bonds are more reactive than
those with only  bonds.
