Question

1. Imagine that you run a mixture of the methylbutene products through GC and you find twolarge peaks. One peak has a retention time of 2.52 minutes and the other peak has a retentiontime of 2.58 minutes.

a. What is likely the identity of the compound responsible for the First Peak? (Circle one)  2-methyl-1-butene  2-methyl-2-butene

b. What is likely the identity of the compound responsible for the Second Peak? (Circle one)  2-methyl-1-butene  2-methyl-2-butene

2. Which peak will most likely have the largest area for the…

Elimination with KOH? (Circle one)  Peak 1           Peak 2         Equal Areas

Elimination with tBuOK? (Circle one)  Peak 1           Peak 2         Equal Areas

3. Which product is which? (Circle one)

a. 2-methyl-1-butene   Zaitsev  Hofmann Neither
