Question

    What is the chemical formula of

    pentane?
    A C₄H₁₀ Correct Answer Incorrect Answer
    B C₅H₅ Correct Answer Incorrect Answer
    C C₅H₁₀ Correct Answer Incorrect Answer
    D C₅H₁₂ Correct Answer Incorrect Answer

    Solution

    Pentane has the chemical formula C₅H₁₂. This follows the pattern of alkane hydrocarbons, where the general formula is CₙH₂ₙ₊₂. For comparison:
    - Methane: CH₄
    - Ethane: C₂H₆
    - Propane: C₃H₈
    - Butane: C₄H₁₀
    - Pentane: C₅H₁₂
    - Hexane: C₆H₁₄
