What final product is expected from the following reaction sequence?

Question

Quizplus · Accepted Answer

The reaction sequence starts with the conversion of methylcyclohexene to 1-bromo-1-methylcyclohexane (I) by reacting with NBS and peroxide. This compound then undergoes a substitution reaction with sodium iodide in acetone to give 1-iodo-1-methylcyclohexane (II). Further, the compound undergoes a Grignard reaction with phenylmagnesium bromide to give the product III, which on treatment with acid will yield the final product, 1-phenyl-1-methylcyclohexane (IV). Hence, option B is the correct answer.
