A tertiary butyl carbocation is more stable than a secondary butyl carbocation because of which of the following ?

A

`-I` effect of `-CH_(3)` groups

B

`+R` effect of `-CH_(3)` groups

C

`-R` effect of `-CH_(3)` groups

D

Hyperconjugation

Text Solution

Verified by Experts

The correct Answer is:
D
`CH_(3) - overset(CH_(3))overset(|) underset((9 alpha H)) underset(CH_3)underset(|)(C^(oplus)) gt CH_(3) - overset(oplus)( C)underset((5 alpha H))(H- CH_(2)) - CH_(3)`
More stable due to Hyperconjugation effect.
