Question

Which one of the following pair represents stereo isomerism?

• A. linkage isomerism and Geometrical
  isomerism
• B. chain isomerism and rotational isomerism
• C. optical isomerism and geometrical
  isomerism
• D. structural isomerism and geometrical
  isomerism

Answer 1

Answer: (C)

optical isomerism and geometrical

isomerism
Stereoisomerism means that the stereoisomers will have same chemical formula and chemical bonds but they have different spatial arrangement. Stereoisomerism includes geometrical isomerism which arises in heteroleptic complexes due to different possible geometrical arrangement of ligands. It also includes optical isomers which are non superimposable mirror images.
