________ is produced when 1 equivalent of HBr is added to hex-1-yne in the presence of peroxides.

Question

Quizplus · Accepted Answer

Addition of one equivalent of HBr to hex-1-yne in the presence of peroxides follows an anti-Markovnikov pathway, leading to the formation of a mixture of E and Z isomers of 1-bromohex-1-ene. This is because the peroxide initiates a radical chain reaction that results in the formation of a less stable secondary radical intermediate, which can rearrange to form the more stable primary radical intermediate, leading to both E and Z isomers. Option A is incorrect as it only accounts for one isomer, and Options B and C are incorrect as they assume formation of only one stereoisomer. Option E is incorrect as it involves the formation of a different compound.
