Question

CH₃ – CH₂ – OH and CH₃ – O – CH₃ are ______.

Options

• position isomers

• chain isomers

• homologous

• functional group isomers

Answer 1

CH₃ – CH₂ – OH and CH₃ – O – CH₃ are functional group isomers.

Explanation:

CH₃ – CH₂ – OH and CH₃ – O – CH₃ are functional group isomers because they have the same molecular formula (C₂H₆O) but belong to different functional groups – ethanol is an alcohol (–OH), while dimethyl ether is an ether (–O–).
