Vedclass · Answer

(D) Ammoniacal $AgNO_3$ (Tollens' reagent) reacts with terminal alkynes $(R-C \equiv CH)$ to form white precipitates of silver acetylides.This reaction occurs because the terminal hydrogen atom in terminal alkynes is acidic in nature.$CH_3-CH(CH_3)-C \equiv CH$ is a terminal alkyne.$HC \equiv CH$ (Acetylene) is a terminal alkyne.$1$-Butyne $(CH_3-CH_2-C \equiv CH)$ is a terminal alkyne.Since all the given compounds are terminal alkynes,they all react with ammoniacal $AgNO_3$.

Which of the following compounds is capable of reacting with ammoniacal $AgNO_3$ solution?
