1 CHM 138H TUTORIAL 7 As described in the course outline, the tutorial quizzes will be based closely upon the textbook questions recommended below for this week's tutorial as well as those recommended in last week's tutorial. You should be able to do the questions below from the course textbook (J. McMurry, 7 th Edition). Please work through them in preparation for Tutorial 7. Chapter 6: 6.1-6.3, 6.5, 6.7, 6.9-6.11, 6.13-6.16, 6.18, 6.19, 6.23-6.25, 6.29-6.31, 6.34, 6.39-6.42, 6.45, 6.46-6.49, 6.51-6.54, 6.57. Of the above, the following represent some of the better questions: 6.14, 6.18, 6.19, 6.31, 6.39, 6.46, 6.47, 6.49, 6.51, 6.52, 6.53, 6.54, 6.57.

Unformatted text preview: 1. Explain why, for the reaction of ethene with HBr, the activation energy of the first step ( G 1 ‡ ) is much greater than the activation energy of the second step ( G 2 ‡ ). 2. Consider the following reaction. Write a detailed mechanism for this transformation, showing electron flow by the use of curved arrows and the structures of all intermediates. Will the product generated exist in stereoisomeric forms? Here are some excellent Flashware animations to take a look at from Chapter 6: Hydrohalogenation of Alkenes (very important) Carbocation rearrangement: 1,2-hydride shift Carbocation rearrangement: 1,2-alkyl shift Cl HCl ether...
