Question

$ CH_{3} CH_{2}OH $ and $ CH_{3}OCH_{3} $ are the examples of

• A. chain isomerism
• B. functional isomerism
• C. position isomerism
• D. metamerism

Answer 1

Answer: (B)

Compounds with same molecular formula but different fucntional groups are called functional isomers and this phenomenon is called functional isomerism
$CH_{3}CH_{2}OH$ and $CH_{3}OCH_{3}$ have different functional groups. (i.e., $— OH$ in alcohol, and $—O—$ in ether), hence they are the example of functional isomerism
