Explanation:

Only I

- **Alkenes** have the general formula \( \text{C}_n\text{H}_{2n} \). They are hydrocarbons with carbon-carbon double bonds.
- **Alkanes** have the general formula \( \text{C}_n\text{H}_{2n+2} \). They are saturated hydrocarbons with single bonds.
- Option I (Alkenes - \( \text{C}_n\text{H}_{2n} \)) is correctly stated.
- Option II (Alkanes - \( \text{C}_n\text{H}_{2n-1} \)) is incorrect as it does not match the known formula for alkanes.
- **Option 2: Only I** is the only correct statement about the general formulas given.

Your selected option: **2 - Only I**.
