Question

Ethanol and methoxymethane exhibit :
a. metamerism
b. tautomerism
c. position isomerism
d. functional group isomerism​

Answer 1

They exhibit d) Functional Group Isomerism.

Ethanol and Methoxymethane exhibit functional isomerism as they have the same molecular formula but different functional groups.

Ethanol has the Hydroxyl group (-OH).

Methoxymethane has the ether functional group ( R-O-R)

They both have the same formula (C2H6O).
