WebDec 15, 2024 · 5.4: Optical Activity. The two enantiomers are mirror images of each other. They are very alike and share many properties in common, like same b.p., m.p., density, color, solubility etc. In fact, the pair of enantiomers have the same physical properties except the way they interact with plane-polarized light. WebThe topic “Optical Isomerism” is covered in Chapter 9 i.e, Coordination Compounds of NCERT Class 12 Chemistry. Candidates can expect 4-5 marks from this portion in the exam. Optical isomerism is a form of stereoisomerism. Isomers are the molecules that possess the same molecular formula but have different atomic arrangements in space.
