Stereoisomerism
Molecules with atoms attached in the same order, but which differ from each other in their spacial or 3D arrangement.
Enantiomers
Opposite configurations at all chiral centres and are mirror images of each other
Diastereoisomers
Opposite configuration at some, but not all chiral centres, and are not mirror images of each other
Chiral carbon Configurational isomerism
Carbon attached to 4 different groups Can be interconverted only by breaking covalent bonds
Conformational isomerism Cis-trans/E/Z isomerism
Can be interconverted by free rotation about sigma bonds Exist when there is restricted rotation around atoms
Optical isomerism
Chirality exists when there is an asymmetric (chiral) carbon
Polarimeter
An instrument to measure the amount and the direction of rotation of plane polarized light
Racemic mixture Steric hindrance
An equal mixture of 2 enantiomers Bulky groups make it difficult for an incoming group to
