Molecules with the same molecular formula but different connectivity:

• Constitutional

• Stereoisomer

• Optical

• Geometric

Molecules with the same molecular formula and connectivity but different arrangements in space:

• Constitutional

• Diastereoisomers

• Stereoisomers

• Geometric

The connectivity between atoms is the same, but there are different spatial arrangements of the atoms, which have non-superimposable mirror images.

• Geometric

• Optical

• Conformational

• Geometric

Compounds that are made up of the same atoms with the same connectivity, but differ in the orientation of those atoms in space. Usually using cis and trans.

• Conformational

• Constitutional

• Geometric

• Optical

Different spatial arrangements of atoms within a molecule while maintaining the same bond connectivity and configuration, especially if chiral:

• Constitutional

• Geometric

• Conformational

• Optical

Stereomer compounds with molecules that are not mirror images of one another and that are not superimposable:

• Diastereoisomer

• Enantiomer

Chiral molecules that are mirror images of one another and are not superimposable.:

• Diastereoisomer

• Enantiomer
