`CH_(3)C-=CHoverset(2HBr)rarr(X)+(Y)`
Identify (X) and (Y) in the above reaction.

Explanation

To solve the reaction \( \text{CH}_3\text{C} \equiv \text{CH} + 2 \text{HBr} \rightarrow (X) + (Y) \), we will follow these steps:

### Step 1: Identify the Reactants
The reactant is an alkyne, specifically 1-butyne (\( \text{CH}_3\text{C} \equiv \text{CH} \)). We are reacting it with 2 moles of HBr.

### Step 2: Understand the Mechanism of the Reaction
HBr dissociates into \( \text{H}^+ \) and \( \text{Br}^- \). The reaction proceeds via an electrophilic addition mechanism, where the \( \text{H}^+ \) can add to either of the carbons involved in the triple bond.
