Define stereoisomer
Same structural formula but different arrangements of atoms in space
Define optical isomers
Compounds that are non superimposable mirror images of each other, containing at least one chiral centre
Define chiral centre
An atom bonded to 4 different types of atoms or groups of atoms
Chemical and physical properties of optical isomers
Identical physical and chemical properties to non chiral reagents and materials
They will react differently to chiral reactants e.g enzyme
