Which one of the following pairs represents stereoisomerism

Answer»

Chain isomerism and ROTATIONAL isomerism
Structural isomerism and geometric isomerism
Linkage isomerism and geometric isomerism
Optical isomerism and geometric isomerism

Solution :When ISOMERS have the structural formula but differ in the relative ARRANGEMENT of atoms of groups in space with in the molecule, these are known as stereoisomers and the phenomenon as stereisomerism. Stereoisomerism is of THREE TYPES (i) Geometrical isomerism (ii) Optical isomerism (iii) Conformational isomerism.
