WebThus, the general guidelines for predicting the number of optical isomers is given as under. 1. When the molecule is unsymmetrical: Number of d and l isomers (a) = 2 n. Number of meso forms (m) = 0. Total number of optical isomers (a + m) = 2 n. where n is the number of chiral carbon atom(s). Common example is CH 3 CH(Br)CH(Br)COOH. 2.
