Vedclass · Answer

(A) Sodium in liquid ammonia $(Na/NH_3(l))$ is a reagent used for the reduction of alkynes to trans-alkenes. However,terminal alkynes (alkynes with a hydrogen atom attached to the triply bonded carbon) react with sodium in liquid ammonia to form sodium acetylide and release hydrogen gas because the terminal hydrogen is acidic. Among the given options,$CH_3-C \equiv CH$ (propyne) is a terminal alkyne,while the others are either internal alkynes or alkenes. Therefore,$CH_3-C \equiv CH$ reacts with sodium in liquid ammonia.
