Vedclass · Answer

(A) The reduction of an alkyne to a $trans$-alkene is achieved using dissolving metal reduction. Sodium $(Na)$ metal in liquid ammonia $(NH_3)$ is the specific reagent used for this transformation,known as Birch reduction or dissolving metal reduction. This reaction proceeds via a radical anion intermediate,which favors the formation of the more stable $trans$-isomer.
