Bond order of gas evolved out when \(\left[\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{NH}_{2}+\left(\mathrm{CH}_{3}\right)_{2} \mathrm{CHNH}_{2}\right]\) is treated with sodium nitrite and \(\mathrm{HCl}\) is
1 2.5
2 2
3 3
4 1
Explanation:
Primary amine and \(\mathrm{HNO}_{2}\) produces nitrogen gas. \(\mathrm{RNH}_{2}+\mathrm{HNO}_{2} \rightarrow \mathrm{ROH}+\mathrm{N}_{2}+\mathrm{H}_{2} \mathrm{O}\) \(\mathrm{N}_{2}\) bond order is 3
CHXII13:AMINES
324193
Select the compound which on treatment with nitrous acid liberates nitrogen.
1 Nitroethane
2 Triethylamine
3 Diethylamine
4 Ethylamine
Explanation:
Primary amines on treatment with nitrous acid liberates nitrogen. Ethylamine \(\left(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{NH}_{2}\right)\) is a primary amine. Hence, liberates nitrogen on treatment with nitrous acid. \(\begin{aligned}& \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{NH}_{2}+\mathrm{HNO}_{2} \stackrel{\mathrm{NaNO}_{2}+\mathrm{HCl}}{\longrightarrow}\end{aligned}\) \({\text{R - }}\mathop {\mathop {\text{N}}\limits^{\text{ + }} \equiv {{\text{N}}^{\text{ - }}}}\limits_{\begin{array}{*{20}{c}}{{\text{Diazonium}}} \\ {{\text{chloride}}} \end{array}} {\text{Cl}}\xrightarrow{{{{\text{H}}_{\text{2}}}{\text{O}}}}{\text{ROH + }}{{\text{N}}_{\text{2}}}{\text{ + HCl}}\)
