Consider the following carbocations, `undersetI((CH_3)_3C overset+CH_2), underset(II)((CH_3)_3C^(+)), CH_(3)underset(III)CH_(2)overset(+)CH_(2), CH_(3
Consider the following carbocations,
`undersetI((CH_3)_3C overset+CH_2), underset(II)((CH_3)_3C^(+)), CH_(3)underset(III)CH_(2)overset(+)CH_(2), CH_(3)underset(IV)overset(+)CH-CH_(3)`
The correct order for the stability of the above carbocations is
A. `IltIIIltIVltII`
B. `IIIltIVltIltII`
C. `IVltIIIltIIltI`
D. `IIltIVltIIIltI`

Correct Answer - A
Larger the number of `alpha-H` atoms linked toa carbocation, more will be stable carbocation. On the basis of hyperconjugation, the correct order of stability is `I lt III lt IV lt II`
