Question

Write the iupac names of isomers of c3h9n which do not liberate nitrogen gas on treatment with nitrous acid

Answer 1

(a)$CH_{3}$-$CH_{2}$-$CH_{2}$-$NH_{2}$

propane-1-amine

(b)N-methylethanamine(sec)

$CH_{3}$-$CH_{2}$-$C_{2}$$H_{5}$

(c)Propane-2-amine(pri)

             $NH_{2}$

                ║

       $CH_{3}$-CH-$CH_{3}$

(d)N,N-Dimethyl methanamine(tert)

              $CH_{3}$

                ║

       $CH_{3}$-N-$CH_{3}$

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

$CH_{3}$$CH_{2}$$CH_{2}$$NH_{2}$+$HNO_{2}$→$CH_{3}$$CH_{2}$$CH_{2}$OH+$N_{2}$+HCL
