Current Question (ID: 21355)

Question:

$\text{Consider the following sequence of reactions:}$ $\text{But-2-yne} \xrightarrow{\text{Na-Liq. NH}_3} \text{A} \xrightarrow{\text{Cold, alkaline, dil. KMnO}_4} \text{B}$ $\text{The number of oxygen atoms present in one molecule of B is/are:}$

Options:

1. $2$
2. $3$
3. $4$
4. $1$

Solution:

$\text{Hint: To form trans-alkene (E-configuration), use sodium metal (Na) in liquid ammonia (NH}_3\text{).}$ $\text{Birch reduction:}$ $\text{Trans-But-2-ene} \xrightarrow{\text{Cold, alkaline, dil. KMnO}_4} (\pm)\text{Butane-2,3-diol (B)}$ $\text{Hence the number of O atom in one molecule of B is 2.}$
