A compound (X) having molecular formula `C_6 H_(10)` gave 2-methylpentane on treatment with `H_2` in the presence of Pd. When treated with dilute `H_2 SO_4` containing `HgSO_4`, it yielded another compound having molecular formula `C_6 H_(12)O `. Compound X did not react with ammonical CuCl and metallic sodium. Identity X.

Explanation

To identify the compound (X) with the molecular formula C₆H₁₀, we can follow these steps:

### Step 1: Determine the type of compound based on the molecular formula.
The molecular formula C₆H₁₀ suggests that the compound could be an alkyne, as it fits the general formula for alkynes (CₙH₂ₙ₋₂).

**Hint:** Remember that the degree of unsaturation can help determine the type of compound. Alkynes have a higher degree of unsaturation than alkenes or alkanes.

### Step 2: Analyze the reaction with hydrogen and palladium.
