Step-by-step solution

The reaction of methylcyclohexane with bromine in the presence of light ( h ) is a free-radical substitution reaction. The mechanism involves the formation of a carbon radical intermediate. The stability of the radical intermediate determines the major product. The possible radicals formed are primary, secondary, or tertiary. The tertiary radical at the C1 position (where the methyl group is attached) is the most stable due to hyperconjugation and inductive effects from the surrounding alkyl groups. Although the te
