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 g mol⁻¹ C : 12, H : 1, O : 16, Cl : 35.5)

Answer

341

Benzyl Amine is most basic due to localised lone pair.

JEE Main 2025 (Online) 29th January Morning Shift Chemistry - Compounds Containing Nitrogen Question 10 English Explanation

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

$$\begin{aligned} & =0.00934 \times 36.5 \\ & =0.341 \mathrm{gm} \\ & =341 \mathrm{mg} \end{aligned}$$
