Hyperconjugation is most useful for stabilizing which of the following carbocations?

A

neo - Pentyl

B

tert - Butyl

C

iso - Propyl

D

Ethyl

Text Solution

Verified by Experts

The correct Answer is:
b
Stability order of different alkyl carbocations on the basis of hyperconjugation is :
`3^(@)gt2^(@)gt1^(@)gt` methyl
In t- butyl cation , the C - atom bearing the positive charge is attached to three methyl groups therefore it possess nine `alpha` hydrogens . It will give maximum nine hyperconjugative structures leading to maximum stability .
