Question

Ethers exbhit which of the following isomerism(s)?

• A. Chain isomerism
• B. Functional isomerism
• C. Metamerism
• D. A, B &C

Answer 1

Answer: (D)

A, B &C

Ethers exhibit chain isomerism ,functional isomerism, Metamerism and Chain isomerism.Ethers with the same formula and having different carbon chain skeletons are called chain isomers.

Functional isomers : Ethers are isomeric with alcohols.

Metamerism Isomers with the same molecular formula but different alkyl groups (around thefunctional group) are called metamers. An ether with formula $C_4{H}_{10}O$ has 3 metamers.

Hence option D is correct.
