Detailed explanation-1: -First one is Alcohol and the second compound is ether. Since there molecular formula are same and one is Alcohol and other is Ether, they are FUNCTIONAL ISOMERS.

Detailed explanation-2: -CH3−CH2−OH and CH3−O−CH3 are example of functional isomerism because isomers which show a difference in the functional group present in the carbon chain is known as functional isomerism.

Detailed explanation-3: -For which of the following parameters the structural isomers ‘C 2H 5OH and CH 3OCH 3‘ would be expected to have the same values ? Solution : Gaseous density at same temperature and pressure as molar mass is same .

Detailed explanation-4: -Hence dimethyl ether (CH3−O−CH3) is an isomer of ethanol.
