Question

Why the ease of dehydration of alcohols follows sequence, tertiary>secondary>primary?

• A. Tertiary alcohol reacts with acids faster followed by secondary and then primary.
• B. Because tertiary alcohol is least stable followed by secondary and then primary alcohol.
• C. Tertiary alcohol is most reactive of all while primary is the least reactive
• D. Because carbocation is the intermediate formed and their stability order is also tertiary>secondary>primary.

Answer 1

The correct option is D

Because carbocation is the intermediate formed and their stability order is also tertiary>secondary>primary.

Dehydration of alcohol has carbocation intermediate whose stability order is tertiary>secondary>primary.
