Question

Which phenomenon is not shown by alkenes?

• A. Chain isomerism
• B. Geometrical isomerism
• C. Metamerism
• D. Position isomerism

Answer 1

The correct option is C

Metamerism

Metamerism is a special type of isomerism which is due to the difference in the nature of alkyl groups attached to polyvalent atoms or functional groups. Compounds like ethers,thio-ethers,ketones,secondary amines,etc do not exhibit metamerism.
