Metamerism is only shown by:
Correct answer: C. Both a and b
- A. Ethers
- B. Ketones
- C. Both a and b
- D. Every organic family
Explanation
As option A suggests, ethers can exhibit metamerism. Metamerism is a type of structural isomerism where the compounds have the same molecular formula but differ in the nature or sequence of atoms within the molecule. In ethers, metamerism occurs when the alkyl groups on either side of the oxygen atom are different and as option b suggests that Ketones can also exhibit metamerism. This happens when the alkyl groups attached to the carbonyl group are different. Therefore, option c is correct.

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
