#6.2.2a
the general formula for an α-amino acid as RCH(NH2)COOH and the following reactions of amino acids:
(i) reaction of the carboxylic acid group with alkalis and in the formation of esters (see also 6.1.3c)
(ii) reaction of the amine group with acids
#6.2.2b
structures of primary and secondary amides (see also 6.1.3f, 6.2.3a–b)
#6.2.2c
optical isomerism (an example of stereoisomerism, in terms of non-superimposable mirror images about a chiral centre) (see also 4.1.3c–d)
Learners should be able to draw 3-D diagrams to illustrate stereoisomerism.
#6.2.2d
identification of chiral centres in a molecule of any organic compound.
