Question

which of the following undergoes dehydration more easily
A.primary alcohol
B.Secondary alcohol
C.Tertiary alcohol
D.all undergo dehydration with the same ease​

Answer 1

Primary alcohols are dehydrated easily than secondary and teritary alcohols.

Hence option A is correct.

Answer 2

Answer:

A) primary alcohol

Explanation:

Dehydration of alcohols involves the formation of a carbocation intermediate.

Higher the stability of carbocation, higher is the ease of dehydration.

The order of stability of carbocation is Tertiary>Secondary>Primary

On dehydration, tertiary alcohol forms tertiary carbocation, secondary alcohol forms secondary alcohol, tertiary alcohol forms tertiary carbocation.

From the figure, we can see that only 2-phenyl-2-butanol is a tertiary phenol. So, it would undergo dehydration most readily.
