In the reaction with HCl , an alkene reacts following the Markovnikov's rule to give the product 1 - chloro - 1 - methylcyclohexane. The possible reaction of the alkene is

Step-by-step solution

The Markovnikov's rule asserts that with the addition of a protic acid HX to an asymmetric alkene, the acid hydrogen ( H ) gets attached to the carbon with more hydrogen substituents and the halide ( X ) group gets attached to the carbon with more alkyl substituents.
