WebStereoisomers differ in their spatial orientation of atoms in the molecule and include geometric isomers (Section 2.2) and also optical isomers. Optical isomers are asymmetric molecules that rotate the plane of polarized light differently depending on the sequence of atoms around the chiral centre. Terminologies include the following: D/L, R/S ... WebThe optical isomers are called dextro and laevo depending upon the direction in which plane of the polarized light is rotated. These d and l isomers of compound are called enantiomers. Example is given above.
