    Question

    What is the chemical formula of propane?

    A.

    C5H10\text{C}_5\text{H}_{10}​​

    B.

    C3H8\text{C}_3\text{H}_{8}​​

    C.

    C2H6\text{C}_2\text{H}_{6}​​

    D.

    CH2\text{CH}_{2}​​

    Correct option is B

    The Correct Answer Is: (b) C₃H₈
    Explanation:
    The chemical formula of propane is C₃H₈. It is a saturated hydrocarbon (alkane) containing three carbon atoms and eight hydrogen atoms. Propane is commonly used as a fuel and is found in natural gas and liquefied petroleum gas (LPG).
    It is a simple alkane and follows the general formula for alkanes, which is CₙH₂ₙ₊₂, where n is the number of carbon atoms in the molecule.
    Information Booster:
    • Use as Fuel: Propane is commonly used as a fuel for heating, cooking, and in certain internal combustion engines.
    • Properties of Alkanes: Propane, like other alkanes, is a colorless, odorless gas at room temperature and pressure and is highly flammable.
    • Nomenclature: Propane belongs to the group of alkanes, which are saturated hydrocarbons (only single bonds between carbon atoms).
    • Natural Occurrence: Propane is a major component of natural gas and is also produced during the refining of crude oil.

    Additional Information:

    • C₅H12: This is the formula for pentane, an alkane with five carbon atoms.
    • C₂H₆: This is the formula for ethane, an alkane with two carbon atoms.
    •  CH₂CH₂: This is the formula for ethylene, an alkene with a double bond between two carbon atoms.
