Vedclass · Answer

(A) Acetylene $(HC \equiv CH)$ is a terminal alkyne with acidic hydrogen atoms attached to $sp$-hybridized carbon atoms.$1$. It reacts with $Na$ to form sodium acetylide $(NaC \equiv CNa)$ and releases $H_2$ gas.$2$. It reacts with ammoniacal $AgNO_3$ (Tollens' reagent) to form a white precipitate of silver acetylide $(AgC \equiv CAg)$.$3$. It reacts with $HCl$ via electrophilic addition to form vinyl chloride and eventually ethylidene chloride.$4$. $NaOH$ is a base,but it is not strong enough to deprotonate the terminal alkyne (which has a $pK_a$ of approximately $25$). Therefore,acetylene does not react with $NaOH$.
