The scenario involves treating 3-methylcyclohexanone with chlorine in acidic conditions, which leads to the formation of a chlorinated product. The task is to determine the major product based on the regioselectivity of the reaction, considering the influence of the ketone and the methyl group on the cyclohexane ring. The correct answer is 2-chloro-3-methylcyclohexanone, as it is the product formed at the most stable position during the reaction."}
