Rate of dehydration of alcohols follows the order:

Options

  1. A2^ >1^ > CH ₃ OH >3^
  2. B3^ >2^ >1^ > CH ₃ OH
  3. C2^ >3^ >1^ > CH ₃ OH
  4. DCH ₃ OH >1^ >2^ >3^

Correct answer

B. 3^ >2^ >1^ > CH ₃ OH

Step-by-step solution

The order of dehydration among three type of alcohols is 3^ >2^ >1^ > CH ₃ OH . This behaviour is related to the relative stabilities of carbocations (3^ >2^ >1^ ) .
