Constitutional Isomers

Compounds that have the same molecular formula but differ in the connectivity of their atoms, leading to different physical and chemical properties.

Diastereomers

Stereoisomers that are not mirror images of each other, containing two or more stereocenters.

Enantiomers

Mirror-image forms of a chiral molecule that cannot be superimposed on each other, often showing different behaviors in chiral environments.
