Which of the following is correct order of ease of dehydration of alcohols?

Correct answer: B. 3o alcohol > 2o alcohol > 1o alcohol

  • A. 1o > alcohol 2o > alcohol 3o alcohol
  • B. 3o alcohol > 2o alcohol > 1o alcohol
  • C. 2o alcohol > 1o alcohol > 3o alcohol
  • D. 3o alcohol > 1o alcohol > 2o alcohol

Explanation

The correct order of ease of dehydration of alcohols is tertiary alcohol > secondary alcohol > primary alcohol. Tertiary alcohols have more stable carbocations, making them easier to dehydrate than secondary alcohols, which are easier than primary alcohols. Options A, C, and D are incorrect because they do not follow this order.
