Question
Which of the following acids does not exhibit optical isomerism ?
Options
A.Maleic acid
B.α - amino acid
C.Lactic acid
D.Tartaric acid
Solution
Only those componds exhibit optical isomerism, which have chiral centre and/ or absence of symmetry elements. (Chiral carbon is the carbon all the four valencies of which are satisfied by four different groups.)

Thus, malic acid does not exhibit optical isomerism.
Note If R = H, the α-amino acid is achiral
