Vedclass · Answer

(A) Acetylene $(HC \equiv CH)$ is a terminal alkyne with acidic hydrogen atoms.$1$. It reacts with strong bases like $NaNH_2$ or metals like $Na$ to form acetylides.$2$. It reacts with ammoniacal $AgNO_3$ (Tollens' reagent) to form a white precipitate of silver acetylide.$3$. It reacts with $HCl$ via electrophilic addition to form vinyl chloride.$4$. $NaOH$ is a strong base but is not strong enough to deprotonate acetylene effectively under standard conditions,and it does not undergo addition reactions with alkynes. Therefore,it does not react with acetylene.
