Question

Question

Predict the major products of acid-catalyzed dehydration of the following alcohols

a. 2-methylpropan-1-ol

Answer 1

Answer #1

a.

но H2o major product

Step 1: Protonation of alcohol gives the oxonium species.

Step 2: Elimination of water.

Step 3: Carbocation rearrangement (primary to more stable secondary).

Step 4: Abstraction of proton gives trans-2-butene as major product.

Answer 2
