Which gas will be evolved out when \([CH_3CH_2NH_2 + (CH_3)_2CHNH_2]\) is treated with sodium nitrite and \(HCl\) :
1 Chlorine
2 Ammonia
3 Nitrogen
4 \(NO_2\)
Explanation:
Primary amine reacts with nitrous acid (obtained from sodium nitrite and \(HCl\) ) to form primary alcohol along with evolution of nitrogen gas. \(CH _3 CH _2 NH _2+\left( CH _3\right)_2 CHNH _2+ HNO _2 \underset{273-278 K }{\stackrel{ NaNO _2+ HCl }{\longrightarrow}} CH _3 CH _2 OH +\left( CH _3\right)_2 CHOH + H _2 O + N _2 \uparrow\)

Highest value of \(pK_b\) will be of :
1 \(NH_3\)
2 \((CH_3)_2NH\)
3 \((CH_3)_3N\)
4 \(CH_3NH_2\)
Explanation:
when a compound attech with alkyl compound so the \(pKb\) value is less so amine \(NH_3\) have highest value of \(Pkb\)

Lowest boiling point will be of the compound :
1 Ethylamine
2 Ethylmethylamine
3 \(1-\) Propaneamine
4 \(N,N-\) Dimethylmethaneamine
Explanation:
\(N,N-\)dimethylmethanamine will have the lowest boiling points as it cannot form hydrogen bonds. Other amines can form hydrogen bonds and have higher boiling points.
