        Stereochemistry
        Stereoisomers are molecules with the same molecular formula but which have a different spatial arrangement of their atoms.
        Optical isomerism
        Optical isomerism occurs in substances in which four different substituent groups are arranged around a central carbon atom called the chiral centre.

      - 4.1 Stereoisomerism
        (a) how stereoisomerism is distinct from structural isomerism and that stereoisomerism encompasses E‒Z isomerism and optical isomerism
        (b) the terms chiral centre, enantiomer, optical activity and racemic mixture
        (c) optical isomerism in terms of an asymmetric carbon atom
        (d) effect of an enantiomer on plane-polarised light
