Current Question (ID: 17674)

Question:

$\text{The most stable conformation of the product of the following reaction is:}$ $\text{C} \equiv \text{CH} \xrightarrow{\text{HBr} / \text{R}_2\text{O}_2 \ (1 \text{ equivalent})} \xrightarrow{\text{HBr} / \text{dark}}$

Options:

1. $\text{Ph} \ \text{CH} \ \text{Br} \ \text{H}$
2. $\text{Ph} \ \text{H} \ \text{Br} \ \text{Br}$
3. $\text{Ph} \ \text{Br} \ \text{H} \ \text{Br}$
4. $\text{Ph} \ \text{H} \ \text{Br} \ \text{H}$

Solution:

$\text{Hint: The final product is vicinal dibromide.}$ $\text{The first reaction is an example of a free radical addition reaction.}$ $\text{The second reaction is an example of an electrophilic addition reaction.}$ $\text{The reaction is as follows:}$ $\text{Ph} - \text{C} \equiv \text{CH} \xrightarrow{\text{HBr} / \text{R}_2\text{O}_2} \text{Ph} - \text{CH} = \text{CHBr} \xrightarrow{\text{HBr} / \text{dark}} \text{Ph} - \text{CH} \ \text{CH}_2$ $\text{The most stable conformation of product is as follows:}$ $\text{Ph} \ \text{H} \ \text{Br} \ \text{Br}$
