Question

A similarity between optical and geometrical isomerism is that:

• A. Each forms equal number of isomers for a given compound
• B. If in a compound one is present then so is the other
• C. Both are included in stereoisomerism
• D. They have no similarity

Answer 1

The correct option is C Both are included in stereoisomerism

Stereoisomerism is the arrangement of atoms in molecules whose connectivity remains the same but their arrangement in space is different in each isomer. It has two different types, configurational and conformational isomerism. Further configurational isomerism can be classified as geometrical and optical isomerism. Thus, geometrical and optical isomerism are part of stereoisomerism.
