Concept:Functional isomers are compounds with the same molecular formula but different functional groups.Explanation:Ethanol, $\mathrm{CH_3CH_2OH}$, has the molecular formula $\mathrm{C_2H_6O}$ and contains the hydroxyl functional group, $-\mathrm{OH}$.Dimethyl ether, $\mathrm{CH_3OCH_3}$, also has the molecular formula $\mathrm{C_2H_6O}$ but contains an ether linkage, $-\mathrm{O}-$.Both compounds have the same number of carbon, hydrogen, and oxygen atoms, so they share the same molecular formula.However, their atoms are arranged differently, giving them different functional groups and different chemical properties.Therefore, ethanol and dimethyl ether are functional isomers of each other.Answer:C. isomers
