1 Dimethyl ether and ethanol are chain isomers.
2 Ethanoic acid and methylmethanoate are position isomers.
3 n-butane andisobutane are functional isomers.
4 Propan-1-ol and propan-2-ol are position isomers.
Explanation:
(d) Functional isomers:
\(\begin{array}{cc}
\mathrm{CH}_3-\mathrm{O}-\mathrm{CH}_3, & \mathrm{CH}_3 \mathrm{CH}_2 \mathrm{OH} \\
\text { (Ether) } & \text { Ethanol } \\
\text { (Alcohol) }
\end{array}\)
