Question
Define: Functional group isomerism
✓
Answer
Different compounds having the same molecular formula but different functional groups are called as futictional group isomers and the phenomenon is called as junctional group isomerism.
e.g. $CH_3 – O – CH_3 ($ Dimethyl ether $)$ and $C_2H_5 – OH ($ ethyl alcohol $)$ have same molecular formula $(C_2H_6O)$ but former has ether $(-O-)$ functional group and the latter has alcoholic $(-OH)$ functional group.
