Which of the following reactions will yield $2, 2-$dibromopropane?

1. $\mathrm{CH}_3-\mathrm{C} \equiv \mathrm{CH}+2 \mathrm{HBr} \longrightarrow$
2. $\mathrm{CH}_3 \mathrm{CH} \equiv \mathrm{CHBr}+\mathrm{HBr} \longrightarrow$
3. $\mathrm{CH} \equiv \mathrm{CH}+2 \mathrm{HBr} \longrightarrow$
4. $\mathrm{CH}_3-\mathrm{CH}=\mathrm{CH}_2+\mathrm{HBr} \longrightarrow$

Solution

Hence, (A) is correct.
