Ethers show functional group isomerism with __________________?
Correct answer: C. alcohols
- A. aldehydes
- B. ketones
- C. alcohols
- D. carboxylic acid
Explanation
Ethers and alcohols can have the same molecular formula but different functional groups, so they show functional-group isomerism. For example, C2H6O can represent ethanol, an alcohol, or dimethyl ether, an ether. Students may choose aldehydes or ketones because they also contain oxygen, but their general formulas do not match ethers and alcohols in this way.

About Isomerism
Isomerism occurs when compounds have the same molecular formula but different atom arrangements or spatial orientations. The content includes chain, position, functional, metameric and tautomeric isomerism, along with geometrical and optical isomerism, including cis-trans forms, E/Z notation, chirality and enantiomers.
