Question

\[\ce{CH3 - CH2 - OH}\] and \[\ce{CH3 - O - CH3}\] are ______.

Options

• position isomers

• chain isomers 

• homologous

• functional group isomers

Answer 1

\[\ce{CH3 - CH2 - OH}\] and \[\ce{CH3 - O - CH3}\] are  functional group isomers.

Explanation:

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