Dimethyl ether and ethyl alcohol are
metamers
homologues
functional isomers
position isomers
C.
functional isomers
(i) Metamers have different alkyl groups attached to same functional group.
(ii) Functional isomers have different functional groups.
(iii) Homologous are represented by same general formula and two successive homologous differ by CH2.
(iv) Position isomers differ in position of double bond or triple bond or functional group.
CH3—O—CH3 CH3CH2OH
(dimethyl ether) (ethyl alcohol)
∴ Dimethyl ether and ethyl alcohol have same formula but different functional groups.
∴ They are functional isomers.
