Question

Write structures of different isomers corresponding to the molecular formula, `C_(3)H_(9)N.` Write IUPAC names of the isomers which will liberate nitrogen gas on treatment with nitrous acid.

Answer 1

The structures of different isomers corresponding to the molecular formula, `C_(3)H_(9)N` are giben below :
(a) `CH_(3)-CH_(2)-CH_(2)-NH_(2)` Propan -1- amine `(1^(@))`
(b) `CH_(3)-overset(NH_(2))overset(|)CH-CH_(3)`
Propan -2- amine `(1^(@))`
(c ) `CH_(3)-NH-C_(2)H_(5)`
N- Methylethanamine `(2^(@))`
(d) `CH_(3)-overset(CH_(3))overset(|)N-CH_(3)`
N N-Dimethylmethanamine `(3^(@))`
`1^(@)` amines, (a) propan-1-amine, and (b) propan-2-amine will liberate nitrogen gas on treatment with nitrous acid.
