Vedclass · Answer

(B) Sodium in liquid ammonia $(Na/NH_3(l))$ is a reducing agent used for the Birch reduction of alkynes to trans-alkenes.However,terminal alkynes (alkynes with a hydrogen atom attached to the triply bonded carbon,$R-C \equiv CH$) react with sodium in liquid ammonia to form sodium acetylide $(R-C \equiv C^- Na^+)$ and release hydrogen gas $(H_2)$.Among the given options,$CH_3-CH_2-C \equiv CH$ is a terminal alkyne,while the others are either internal alkynes or alkenes which do not undergo this specific acid-base reaction with sodium.

Which of the following hydrocarbons reacts with sodium in liquid ammonia?
