WebOptical activity of a molecule is defined as its ability to rotate a plane-polarized (light vibrating in one direction) light that passes through it. Optical activity of a molecule depends on the chirality of the molecule. A chiral molecule is a molecule that is a chiral carbon, i.e., a carbon with four different groups attached to it.
