Vedclass · Answer

(B) The reaction proceeds in two steps:$1$. The reduction of but-$2$-yne $(CH_3-C \equiv C-CH_3)$ with $Na/liq. NH_3$ (Birch reduction) gives trans-but-$2$-ene $(CH_3-CH=CH-CH_3)$.$2$. The subsequent reaction with cold dilute alkaline $KMnO_4$ (Baeyer's reagent) performs syn-hydroxylation of the alkene to form butane-$2,3$-diol $(CH_3-CH(OH)-CH(OH)-CH_3)$.$3$. The product $P$ is butane-$2,3$-diol,which contains $2$ oxygen atoms.

The major product of the following reaction is $P$. Number of oxygen atoms present in product $P$ is $. . . . . . . . . . . (nearest integer)$.
