The order of ractivity of the following alcohols towards concentrated HCl is

A

`I gt II gt III gt IV `

B

`I gt III gt II gt IV `

C

`IV gt III gt II gt I`

D

`IV gt III gt I gt II `

Text Solution

Verified by Experts

The correct Answer is:
A
The order of reactivity depends upon the stability of carbocation formed i.e. stability of carbocations.
`underset(I)(CH_3CH_2overset(+)CHCH_3)lt underset(II)(CH_3overset(+)CHCH_3) lt underset(III)(CH_3CH_2CH_2overset(+)CHCH_3) lt underset(IV)(phoverset(+)CH_2)`
Thus the order of reactivity of alcohols will be `I gt II gt III gt IV`.
