Question

The molecular formula of cyclopentane is

• A. C₅H₁₀
• B. C₅H₁₂
• C. C₅H₈
• D. C₅H₁₂

Answer 1

The Correct Option is A

Cyclopentane is a cyclic hydrocarbon with five carbon atoms in a ring. Each carbon atom forms two single bonds with adjacent carbons and two single bonds with hydrogen atoms. The general formula for a saturated cyclic hydrocarbon with \( n \) carbon atoms is \( \text{C}_n\text{H}_{2n} \). For \( n = 5 \):

\[ \text{Molecular formula} = \text{C}_5\text{H}_{10}. \]

Final Answer: The molecular formula of cyclopentane is \( \mathbf{\text{C}_5\text{H}_{10}} \), which corresponds to option \( \mathbf{(1)} \).
