Which one of the following pairs represents stereoisomerism ?

  1. A
    Chain isomerism and rotational isomerism
  2. B
    Structural isomerism and geometric isomerism
  3. C
    Linkage isomerism and geometric isomerism
  4. D
    Optical isomerism and geometric isomerism

Solution & Step-by-step Explanation

Stereoisomerism refers to isomers that differ in the spatial arrangement of their atoms. Geometric isomerism (also known as cis-trans isomerism) and optical isomerism are both types of stereoisomerism. Geometric isomers differ in the arrangement of atoms or groups in space, typically around a double bond or a ring. Optical isomers are molecules that are mirror images of each other and cannot be superimposed. They differ in their ability to rotate plane-polarized light. Therefore, the correct pair representing stereoisomerism is optical isomerism and geometric isomerism.
