Chemistry - AMINES Question with Solution | TestHub

Question Explanation:

The question asks to determine the correct structural relationship between the given compounds (amines).

Concept: This is based on constitutional (structural) isomerism , including functional isomerism , metamerism , and chain isomerism .

Solution:

(i) Compound I is a primary $\left(1^{\circ }\right)$ amine and II is a secondary $\left(2^{\circ }\right)$ amine; therefore, they are functional isomers.

(ii) The given compounds are metamers, as they differ in the alkyl groups attached to the same functional group ( $2^{\circ }$ amine).

(iii) Compounds I and IV differ in functional groups; hence, they are functional isomers.

(iv) Compounds I and III differ in the carbon chain arrangement/length, so they are chain isomers.

Final Answer: Option (A), (B) and (D)
