Question

The following compounds,
(a) Propan-1-amine
(b) N-Methylethan-1-amine
(c) N,N-Dimethylmethanamine
are related as :

• A. Not isomers.
• B. Positional isomers.
• C. Functional isomers.
• D. Chain isomers.

Answer 1

The correct option is C Functional isomers.

Structures of (a) , (b) and (c) are :


Structural isomers which show a difference in the functional groups present in the carbon chain are functional isomers.
For the given compounds, the functional groups present are $1^{\circ },2^{\circ }$ and $3^{\circ }$ amine.
So, these compounds are functional isomers.
