Which of the following is NOT a pair of functional isomers?
1 \(\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{OH}\) and \(\mathrm{CH}_3 \mathrm{OCH}_3\)
2 \(\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{NO}_2\) and \(\mathrm{H}_2 \mathrm{NCH}_2 \mathrm{COOH}\)
3 \(\mathrm{CH}_3 \mathrm{COOH}\) and \(\mathrm{HCOOCH}_3\)
4 \(\mathrm{C}_2 \mathrm{H}_5 \mathrm{OC}_2 \mathrm{H}_5\) and \(\mathrm{C}_3 \mathrm{H}_7 \mathrm{OCH}_3\)
Explanation:
(d) Compounds having the same molecular formula but different functional groups are called functional isomers.
Compounds \(\mathrm{C}_2 \mathrm{H}_5 \mathrm{OC}_2 \mathrm{H}_5\) and \(\mathrm{C}_3 \mathrm{H}_7 \mathrm{OCH}_3\) having the same functional group, here only position of oxygen is changed. So, these are not functional isomers but metamers.
