1. Consider the following reaction coordinate diagram. (20) a. What is the rate determining step in the conversion of A to G? b. How many steps is the reaction from A to G? c. Is the conversion from A to E exergonic or endergonic? d. What is the fastest step in this reaction coordinate diagram? 2. Draw a reaction coordinate diagram for the electrophilic addition of HBr to propene where only the Markovnikov pathway is represented. Include a structure at each point. For instance, in question 1, each letter corresponds to either a neutral compound, intermediate, or transition state intermediate. (30)
