Q. In the reaction with HCl, an alkene reacts in accordance with the Markovnikov's rule, to give a product 1-chloro-1-methylcyclohexane. The possible alkene is :- (A) Methylenecyclohexane ($C_6H_{10}=CH_2$) (B) 1-Methylcyclohexene

A) Methylenecyclohexane (A)
B) 1-Methylcyclohexene (B)
C) (A) and (B)
D) 3-Methylcyclohexene
Explanation

[Solution] Both methylenecyclohexane and 1-methylcyclohexene are protonated (Markovnikov) to the same 3° 1-methylcyclohexyl cation, which adds $Cl^-$ to give 1-chloro-1-methylcyclohexane. Answer (3).
