Q. Explain about Optical Isomerism?
Optical Isomerism: -Two isomers which have almost identical physical and chemical properties like mp. B p. density. Colour etc.. But differ in the way they rotate the plane-polarised light are called optical isomers. Such optically active compounds exist in pairs and are known as stereoisomers or enantiomers. These isomers are non-super imposable mirror images of each other. Hence any molecule which contains either a-centre of symmetry or a plane of symmetry will not show optical isomerism.
Optical isomerism is rarely observed in square planar complexes. Tetrahedral complexes of the type [M(AB)2] do give optical isomers as shown in Fig, especially where / M = Be, B etc.
However optical isomerism very common with octahedral complexes of the type! M (AA)3. M(AA)2ab, M(AA)a2,b2. M(AA)(BB)a2 etc. A few typical examples.
Tetracyclines: The tetracyclines consist of hydronapht-hacene skeleton like the characteristic structural unit. The structures of tetracycline are specified as follows,
