Which of the following types of structural isomerism is present inCH3CH2OH and CH3OCH3?
Correct answer: D. Functional group isomerism
- A. Metamerism
- B. Chain isomerism
- C. Tautomerism
- D. Functional group isomerism
Explanation
The compounds having the same molecular formula but different functional groups are said to exhibit functional group isomerism. For example, there are two compounds having the same molecular formula C2H6O , but different arrangement of atoms. These are CH3CH2OH (alcohol) and CH3OCH3 (ether).

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.
