Current Question (ID: 17663)

Question:

$[A]$ $\text{and}$ $[B]$ $\text{in the mentioned reaction are respectively:}$

Options:

1. $\text{Alc. KOH and NaNH}_2$
2. $\text{NaNH}_2 \text{and Lindlar catalyst}$
3. $\text{NaNH}_2 \text{and alcoholic KOH}$
4. $\text{Lindlar catalyst and NaNH}_2$

Solution:

$\text{Hint: Ethanolic potassium hydroxide is used to convert terminal triple bond to non-terminal triple bond.}$ $\text{NaNH}_2/\text{liqNH}_3 \text{is used to convert non-terminal triple to terminal triple bond.}$ $\text{CH}_3 - \text{CH} = \text{C} - \equiv \text{C} - \text{H} \xrightarrow{\text{Alc. KOH}} \text{CH}_3 - \text{C} \equiv \text{C} - \text{CH}_3$ $\text{Alc KOH is relatively weak base which abstract H from sp}^3 \text{hybridized carbon}$ $\text{The isomerization of 2-butyne to 1-butyne can be achieved by treatment with NaNH}_2/\text{liqNH}_3.$ $\text{It can be an excellent nucleophile It's used for deprotonation of weak acids}$
