24. Which one of the following pairs represents stereoisomerism?

[2005]

(a) Structural isomerism and Geometrical isomerism

(b) Optical isomerism and Geometrical isomerism

(c) Chain isomerism and Rotational isomerism.

(d) Linkage isomerism and Geometrical isomerism

Show Answer

Answer:

Correct Answer: 24.(b)

Solution:

  1. (b) Optical and geometrical isomerism pair up to exhibit stereoisomerism. This is because the isomers differ only in their orientation in space.
