What is the correct order of decreasing stability of the following cations
I. `CH_(3) - overset(oplus)(C) H - CH_(3)` II. `CH_(3) - overset(oplus)(C)H - OCH_(3)`
III. `CH_(3) - overset(oplus)(C)H - CH_(2) - OCH_(3)`

A

`II gt I gt III`

B

`II gt III gt I`

C

`III gt I gt II`

D

`I gt II gt III`

Text Solution

Verified by Experts

The correct Answer is:
A
Stability of the given cations can be understood by the following structures

Hence, the stability of carbocation decreases II > I > III
