Chapter 9, Problem 116P

Two elimination products are obtained from the following E2 reaction:

${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CHDCH}}_{\text{2}}\text{Br }\underset{\to }{{\text{CH}}_{\text{3}}{\text{O}}^{\text{-}}}$

1. a. What are the elimination products?
2. b. Which is formed in greater yield? (Hint: See Problem 91.)
