Current Question (ID: 17610)

Question:

$3\text{-Hexyne can be converted to trans-3-Hexene by the action of:}$

Options:

1. $\text{H}_2 \text{- Pd/ BaSO}_4$
2. $\text{Li-Liq. NH}_3$
3. $\text{H}_2 \text{- Pt O}_2$
4. $\text{NaBH}_4$

Solution:

$\text{Hint: The reaction is an example of Birch reduction}$ $\text{When an alkyne reacts with Li or Na in the presence of liq. ammonia then}$ $\text{trans alkene is obtained as a product. The reaction is known as birch}$ $\text{reduction.}$ $\text{The reaction is as follows:}$ $\text{H}_3\text{C} \equiv \text{C} \text{CH}_3 \xrightarrow{\text{Na/NH}_3} \text{H} \text{C} \text{=} \text{CH} \text{CH}_3$
