MCQ
Dimethyl ether and ethyl alcohol are
- ABranched isomer
- BPosition isomer
- ✓Functional isomer
- DTautomer
✓
Answer
Correct option: C.
Functional isomer
c
$(i)$ Metamers have different alkyl groups attached to same functional group.
$(i)$ 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 $CH _2$
$(iv)$ Position isomers differ in position of double bond or triple bond or functional group
$\underset{\text { dimethyl ether }}{ CH _3- O - CH _3} \quad CH _3 CH _2 OH$
Dimethyl ether and ethyl alcohol have same formula but different functional groups.
$\therefore$ They are functional isomers.
