Q. Which amongst the following is the most stable carbocation ?
A) (CH₃)₂C⁺H
B) (CH₃)₃C⁺
C) C⁺H₃
D) CH₃C⁺H₂
Explanation
[Solution from source] Carbocation stability is 3° > 2° > 1° > methyl because of hyperconjugation and the +I effect of alkyl groups. (CH₃)₃C⁺ is tertiary and most stable; the methyl cation is least stable. Answer (2).
