Vedclass · Answer

(C) $1$-butyne is a terminal alkyne $(CH_3-CH_2-C\equiv CH)$,which contains an acidic hydrogen atom attached to the $sp$-hybridized carbon.$2$-butyne $(CH_3-C\equiv C-CH_3)$ is an internal alkyne and does not have an acidic hydrogen.Terminal alkynes react with ammoniacal cuprous chloride $(Cu_2Cl_2/NH_4OH)$ to form a characteristic red precipitate of copper$(I)$ acetylide $(CH_3-CH_2-C\equiv C-Cu)$.Internal alkynes do not give this reaction,thus allowing them to be distinguished.
