In organic chemistry, what is the principal difference between constitutional isomers and stereoisomers?
- Stereoisomers have different molecular formulas, whereas constitutional isomers share the same formula.
- Constitutional isomers differ in atomic connectivity, while stereoisomers differ only in spatial arrangement.
- Constitutional isomers are always mirror images of each other, while stereoisomers are not.
- Stereoisomers involve different functional groups, while constitutional isomers involve the same groups in different places.
