MCQ
Which gas will be evolved out when $[CH_3CH_2NH_2 + (CH_3)_2CHNH_2]$ is treated with sodium nitrite and $HCl$ :
  • A
    Chlorine
  • B
    Ammonia
  • Nitrogen
  • D
    $NO_2$

Answer

Correct option: C.
Nitrogen
c
Primary amine reacts with nitrous acid (obtained from sodium nitrite and $HCl$ ) to form primary alcohol along with evolution of nitrogen gas.

$CH _3 CH _2 NH _2+\left( CH _3\right)_2 CHNH _2+ HNO _2 \underset{273-278 K }{\stackrel{ NaNO _2+ HCl }{\longrightarrow}}  CH _3 CH _2 OH +\left( CH _3\right)_2 CHOH + H _2 O + N _2 \uparrow$
