Step 1
Homomers : Two isomers having superimposable relationship with each other are called homomers.
Enantiomers : Two isomers having non-superimposable mirror image relationship are called enantiomers.
Diasteromers : Two isomers having non-superimposable no mirror image relationship are called diasteromers.
Meso : Compound having plane of symmetry is called meso form.
Constitutional isomers : Two compounds having same molecular formula but different in structure/stereochemistry are called constitutional isomers.
