Chem 334 - Fall 1998 - Organic Chemistry
I 1. (1 point) The major reactions of alkenes are additions to the double bond. When Br2 adds to propene, give the name and structure of the major product.
2. (1 point) When HBr adds to propene, there are two possible products, but according to Markovnikov's Rule, only one product is formed. Give the name and structure of the major product.
3. (1 point) When Br2 adds to cyclopentene, there are two possible stereoisomeric products, but because of the mechanism of anti addition, only one product is formed. Give the name and structure of the major product.
4. (2 points) Write a simple potential energy diagram for a reaction of A to give B, clearly locating the activation energy (Ea), the heat of reaction (delta H), and the transition state.
