What si the correct order of decreasing stability of the following carbocations.
`underset(I.)(CH_(3)-overset(o+)(C)H-CH_(3))" "underset(II.)(CH_(3)-overset(o+)(C)H-OCH_(3))`
`underset(III.)(CH_(3)-overset(o+)(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

Thus, the stability of carbocations decreases in the order: `II gt I gt III`, i.e., option (a) is correct.
