What Cambridge says you should be able to do, in our words. Codes are the topic number plus the objective’s position.
Understand that enantiomers have identical physical and chemical properties apart from their ability to rotate plane-polarised light and their potential biological activity.

Understand and use the terms optically active and racemic mixture.

Describe the effect on plane-polarised light of the two optical isomers of a single substance.

Explain the relevance of chirality to the synthetic preparation of drug molecules, including: (a) the potential different biological activity of the two enantiomers; (b) the need to separate a racemic mixture into two pure enantiomers; (c) the use of chiral catalysts to produce a single pure optical isomer.
Candidates should appreciate that compounds can contain more than one chiral centre, but knowledge of meso compounds and of nomenclature such as diastereoisomers is not required.
