Which of the following acids does not exhibit optical isomerism?Optical isomerism needs a chiral centre.
Tartaric acid, lactic acid and $\alpha$-amino acids (except glycine) have chiral carbon atoms.
Maleic acid, cis-$HOOC-CH=CH-COOH$, has no chiral carbon and has a plane of symmetry, so it does not show optical isomerism (it shows geometrical isomerism).
