The reaction of cyclohexene and Cl₂ yields

Question

Quizplus · Accepted Answer

The reaction of cyclohexene with Cl₂ under normal conditions (room temperature and atmospheric pressure) is a halogenation reaction where the double bond is broken and each chlorine atom adds to a different carbon atom of the ring, forming a mixture of 1,2-dichlorocyclohexane and 1,4-dichlorocyclohexane. However, 1,2-dichlorocyclohexane is the major product because it is thermodynamically more stable than 1,4-dichlorocyclohexane due to the axial-equatorial arrangement of the chlorine atoms. Therefore, the best choice is B, 1,2-dichlorocyclohexane.
