Nitrogen

Vedclass · Answer

(C) Primary aliphatic amines react with nitrous acid $(HNO_2)$,which is generated in situ by the reaction of $NaNO_2$ and $HCl$,to form unstable diazonium salts that decompose to yield primary alcohols,water,and nitrogen gas $(N_2)$.The reaction is as follows:$CH_3CH_2NH_2 + (CH_3)_2CHNH_2 + 2HNO_2$ $\xrightarrow[273-278 \ K]{NaNO_2 + HCl} CH_3CH_2OH + (CH_3)_2CHOH + 2H_2O + 2N_2 \uparrow$Thus,the gas evolved is nitrogen $(N_2)$.

Which gas will be evolved out when $[CH_3CH_2NH_2 + (CH_3)_2CHNH_2]$ is treated with sodium nitrite and $HCl$?
