Which of the following alkenes will yield a meso dihalide when reacted with Br₂/CCl₄ at room temperature? E) both Band D

Question

Quizplus · Accepted Answer

To yield a meso dihalide, the alkene must have a plane of symmetry. Among the given options, only option B has a plane of symmetry passing through both the double bond and the carbon attached to the bromine atoms. Therefore, the reaction of option B with Br2/CCl4 at room temperature will yield a meso dihalide. Option A, C, D all lack a plane of symmetry passing through the double bond and the carbon attached to the bromine atoms, so they will not yield a meso dihalide. Option E is incorrect because option D alone is sufficient to yield a meso dihalide.
