Which of the following is a functional isomer of Dimethyl ether?

Which of the following is a functional isomer of Dimethyl ether? Correct Answer Ethanol

The correct answer is Option 1) i.e Ethanol.

Concept:

  • Functional isomers:
    •  It has the same chemical formula but different functional groups attached to them.
    • e.g C3H6O 
    • It has two functional isomers i.e

Explanation:

  • Dimethyl ether - C2H60
  • It has two functional isomers.
  • The structure is given below:

Notes:

  • Some functional groups show functional isomerism:
    • Alcohols and ethers
      • Ethanol and methoxymethane - functional group isomers of C2H6O
    • Aldehydes and ketones
      • Propanal and propanone - functional group isomers of C3H6O
    • Carboxylic acids and esters
      • Propanoic acid and methyl ethanoate - functional group isomers of C3H6O2
