NEET levelSingle correct optionDifficulty 1 of 3o4093

The correct order of ease of acid-catalysed dehydration of alcohols is

  1. Atertiary > secondary > primary
  2. Bprimary > secondary > tertiary
  3. Cprimary > tertiary > secondary
  4. Dsecondary > tertiary > primary

Answer: A

Acid-catalysed dehydration usually goes through a carbocation (E1), and the ease of formation of carbocations follows . Hence tertiary alcohols dehydrate most easily.
