2. (5 pts) Consider the following energy diagram for the conversion ofA ➫ B ➫ C ➫ D.
a) How many steps are present in the reaction mechanism?
b) Label the transition state (TS) and Ea for each step, and the ΔHo overall for the reaction.
c) Which step is the rate-determining step?
d) What does the transition state structure of the final reaction step (C D)
look like? Choose one from A, B, C, D.
3. (24 pts) Draw the major product of each reaction, and indicate the
stereochemistry where appropriate.
