Optical activity class 12 chemistry
WebDec 15, 2024 · Optical Activity of Different Samples When a sample under measurement only contain one enantiomer, this sample is called as enantiomerically pure, means only … WebIt varies for every molecule which is why optical activity has to be determined experimentally. Each center would have its own contribution like you mentioned but since the centers work together to rotate light I would assume the individual contributions change depending on the other groups.
