Hyperconjugation

Vedclass · Answer

(A) The tertiary butyl carbocation $( (CH_3)_3C^+ )$ has $9$ $\alpha$-hydrogens,whereas the secondary butyl carbocation $( CH_3CH^+CH_2CH_3 )$ has $5$ $\alpha$-hydrogens.Stability of carbocations is directly proportional to the number of hyperconjugative structures,which in turn is determined by the number of $\alpha$-hydrogens.Since the tertiary butyl carbocation has more $\alpha$-hydrogens,it is more stable due to hyperconjugation.

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