Question

The given compounds show which type of isomerism?
and

• A. Chain isomerism
• B. Positional isomerism
• C. Metamerism
• D. Functional group isomerism

Answer 1

The correct option is C Metamerism

Metamerism :
Structural isomers in which there is a difference in the relative position of alkyl group around polyvalent atom/functional groups.

In the given compound the relative position of cyclohexane and benzene is altered between $S{O}_3$ functional group. Thus, these compounds shows metamerism.
