Question
Given below are some nitrogen containing compounds.
Image
Each of them is treated with HCl separately. 1.0 g of the most basic compound will consume _____________ mg of HCl .
(Given molar mass in $\mathrm{g} \mathrm{mol}^{-1} \mathrm{C}: 12, \mathrm{H}: 1, \mathrm{O}: 16$, $\mathrm{Cl}: 35.5)$

Answer

(341)
Sol.
Benzyl Amine is most basic due to localised lone pair.
Image
Mole of benzyl Amine $\Rightarrow \frac{1}{107}=0.00934$ mole
1 Mole of Benzyl amine consumed 1 mole of HCl
So, Mole of HCl consumed $\rightarrow 0.00934$ mole
Mass of HCl consumed $\rightarrow 0.00934 \times$ molar mass of HCl
$
\begin{aligned}
& =0.00934 \times 36.5 \\
& =0.341 \mathrm{gm} \\
& =341 \mathrm{mg}
\end{aligned}
