Problem

Draw and name two different functional group isomers that can have the following molecular formulas: (a) C3H8O\text{C}_3\text{H}_8\text{O} (b) C3H6O\text{C}_3\text{H}_6\text{O} (c) C3H6O2\text{C}_3\text{H}_6\text{O}_2
Intuitive explanation

Functional group isomers have the same molecular formula but different functional groups, which completely changes their chemical properties and reactivity. The key is to think about which functional groups can be "swapped" while keeping the same number of atoms—for instance, an alcohol and an ether, or an aldehyde and a ketone. Once you pick your formula, systematically explore what different arrangements of C, H, and O (or N) allow, then draw the structures and identify each group clearly.
