Loss of a hydride ion from a C-H bond of the compound shown can give two different carbocations. The one formed preferentially is
Athe primary cation, because it is the least hindered
Bthe tertiary cation, stabilised by the +I effect and hyperconjugation of three methyl groups
Ca secondary cation, because it is intermediate
Dboth cations equally
Answer: B
The compound shown is isobutane. Removal of H- from the CH carbon gives a tertiary cation, stabilised by the +I effect and hyperconjugation of three methyl groups. Removal from a CH3 gives a primary cation, which is much less stable.
