Question

Which of the following is a dynamic isomerism?

• A. Metamerism
• B. Geometrical isomerism
• C. Tautomerism
• D. Optical isomerism

Answer 1

The correct option is C Tautomerism

In tautomerism, there is an equlibrium exist between the two tautomers. By changing the conditions, the tautomers can be interconverted. In the other given type of isomerisms, there is no equilibrium between the isomers.

Example: Keto- enol tautomerism of aldehydes and ketones. Keto form and enol form concentration can be controlled by changing the condition of the solution.
