Vedclass · Answer

(C) $1-$Butyne is a terminal alkyne $(CH_3CH_2C\equiv CH)$,which contains an acidic hydrogen atom attached to the $sp$ hybridized carbon.Tollen's reagent (ammoniacal silver nitrate) reacts with terminal alkynes to form a white precipitate of silver alkynide,whereas $2-$butyne $(CH_3C\equiv CCH_3)$ is an internal alkyne and does not react with Tollen's reagent.The reaction is:$CH_3CH_2C\equiv CH + [Ag(NH_3)_2]^+ + OH^- 	o CH_3CH_2C\equiv CAg \downarrow (	ext{white ppt.}) + 2NH_3 + H_2O$
