Question

Quizplus · Accepted Answer

Hex-3-yne can be converted to (Z)-hex-3-ene by hydrogenation over Lindlar's catalyst, which selectively reduces the alkyne to an alkene without further reduction to an alkane. Therefore, the correct answer is C, which shows the use of H₂ (H2) with Lindlar's catalyst. The other reagents listed either do not lead to the desired product or would over-reduce the alkyne to an alkane.
