Vedclass · Answer

(C) The reaction of an internal alkyne like $2-$butyne with sodium metal $(Na)$ in liquid ammonia $(NH_3)$ is a dissolving metal reduction. This reaction proceeds via a radical anion intermediate and results in the anti-addition of hydrogen atoms across the triple bond. Consequently,the product formed is the $trans-$isomer of the corresponding alkene. $CH_3-C \equiv C-CH_3 \xrightarrow{Na/Liq. NH_3} trans-CH_3-CH=CH-CH_3$

$2-$Butyne reacts with $Na$ in liquid $NH_3$ to form:
