Question

Optical isomerism is a type of ____________

(a) metamerism

(b) stereoisomerism

(c) geometrical isomerism

(d) tautomerism

This question was addressed to me in an online interview.

The doubt is from Organic Chemistry topic in chapter Organic Chemistry – Basic Principles and Technique of Chemistry – Class 11

Answer 1

Correct option is (b) stereoisomerism

To elaborate: The compounds having the same molecular formula but the different spatial arrangement of atoms or groups are stereoisomers and the phenomenon is called stereoisomerism. it is of three types namely optical isomerism, geometrical isomerism, and conformations.
