Vedclass · Answer

(B) Terminal alkynes contain an acidic hydrogen atom attached to an $sp$-hybridized carbon atom.These acidic protons can be removed by strong bases like sodium metal in liquid ammonia ($NaNH_2$ is formed in situ or sodium acts as a reducing agent for the proton) to form sodium acetylides.Among the given options,$CH_3CH_2C \equiv CH$ is a terminal alkyne,whereas the others are internal alkynes.Therefore,$CH_3CH_2C \equiv CH$ reacts with sodium in liquid ammonia.

The hydrocarbon which can react with sodium in liquid ammonia is
