Question
Write structures of different isomers corresponding to the molecular formula, C3H9N. Write IUPAC names of the isomers which will liberate nitrogen gas on treatment with nitrous acid.

Answer

  1. $\text{CH}_3-\text{CH}-2-\text{CH}_2-\text{NH}_2$

Propan - 1 - amine(pri)

  1. Propan - 2 - amine (pri)

$ \ \ \ \ \ \ \ \ \ \ \ \text{NH}_2\\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |\\\text{CH}_3-\text{CH}-\text{CH}_3$

  1. $\text{CH}_3-\text{CH}_2-\text{C}_2\text{H}_5$

N-methylethanamine (Sec)

primary amine, (a) Propan - 1 - amine, and (b) Propan - 2 - amine will liberate nitrogen gas on treatment with nitrous acid.

$\text{CH}_3\text{CH}_2\text{CH}_2\text{NH}_2+\text{HNO}_2\rightarrow\text{CH}_3\text{CH}_2\text{CH}_2\text{OH}+\text{N}_2+\text{HCl}\\\text{Propan-1-amine} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{Propan-1-ol}$
