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.
