Assertion : Ease of dehydraction of alco...

Assertion : Ease of dehydraction of alcohols follows the order : Tertiary `gt` Secondary `gt` Primary.
Reason : Dehydration proceeds through the formation of oxonium ion.

A

If both assertion and reason are correct and reason is correct explanation for assertion.

B

If both assertion and reason are correct but reason is not correct explanation for assertion.

C

If assertion is correct but reason is incorrect.

D

If assertion and reason both are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
B
Correct explanation : Dehydration proceeds through the formation of carbocation intermediate in the rate determining step. The relative stabilities of the carbocations are in the order : tertiary `gt` secondary `gt` primary. Oxonium ion is formed by the protonation of alcohol in the first step.
