    Question

    A compound has the molecular formula C2H6O\text{C}_2\text{H}_6\text{O}​. The name of the compound is-

    A.

    Ethanol

    B.

    Both dimethyl ether and ethanol

    C.

    Ethanoic acid

    D.

    Dimethyl ether

    Correct option is B

    The correct answer is (b) Both dimethyl ether and ethanol.
    The molecular formula C₂H₆O can represent two different compounds: ethanol and dimethyl ether. These two compounds are structural isomers, meaning they have the same molecular formula but different structural arrangements of atoms.

    1. Ethanol (C₂H₆O):

      • Structure: CH₃CH₂OH (ethanol has a hydroxyl group -OH attached to an ethyl group).

      • Common Usage: Ethanol is widely used in alcoholic beverages, as a solvent, and in hand sanitizers.

    2. Dimethyl Ether (C₂H₆O):

      • Structure: CH₃OCH₃ (dimethyl ether consists of two methyl groups (-CH₃) bonded to an oxygen atom).

      • Common Usage: Dimethyl ether is used as a propellant in aerosol cans and as a refrigerant.

    Additional Information on Other Options:

    • (C) Ethanoic acid (C₂H₄O₂):

      • This is incorrect because ethanoic acid (acetic acid) has the molecular formula C₂H₄O₂, not C₂H₆O.

    • (D) Dimethyl Ether (C₂H₆O):

      • While dimethyl ether is indeed one of the compounds with the formula C₂H₆O, it is not the only possible compound with that formula, as ethanol is another compound with the same formula.
