Vedclass · Answer

(A) $But-1-yne$ $(CH_3CH_2C \equiv CH)$ is a terminal alkyne with an acidic hydrogen atom attached to the $sp$ hybridized carbon.Terminal alkynes react with ammoniacal silver nitrate ($AgNO_3 + NH_4OH$,also known as Tollen's reagent) to form a white precipitate of silver acetylide $(CH_3CH_2C \equiv CAg)$.$But-2-yne$ $(CH_3C \equiv CCH_3)$ is a non-terminal alkyne and does not have an acidic hydrogen atom,so it does not react with ammoniacal silver nitrate.Therefore,$(AgNO_3 + NH_4OH)$ is used to distinguish between them.
