Vedclass · Answer

(C) Ammoniacal silver nitrate (Tollens' reagent) reacts with terminal alkynes,which possess an acidic hydrogen atom attached to the $sp$-hybridized carbon atom,to form white precipitates of silver acetylides.$CH \equiv CH$,$CH_3 - C \equiv CH$,and $Cl - CH_2 - C \equiv CH$ are terminal alkynes and contain acidic hydrogen atoms.$CH_3 - C \equiv C - CH_3$ (But$-2-$yne) is an internal alkyne and lacks an acidic hydrogen atom.Therefore,it does not react with ammoniacal $AgNO_3$ to form a precipitate.

Which of the following does not give a white precipitate with ammoniacal $AgNO_3$?
