Vedclass · Answer

(B) Terminal alkynes,which contain an acidic hydrogen atom attached to an $sp$-hybridized carbon atom $(-C \equiv CH)$,can react with strong bases like sodium amide $(NaNH_2)$ or sodium metal in liquid ammonia to form acetylides.In the given options,$CH_3CH_2C \equiv CH$ is a terminal alkyne.The reaction is: $CH_3CH_2C \equiv CH + Na \rightarrow CH_3CH_2C \equiv C^-Na^+ + \frac{1}{2}H_2$.Internal alkynes (options $A$ and $D$) and alkenes (option $C$) do not have acidic terminal hydrogen atoms and therefore do not react with sodium in liquid ammonia.
