Vedclass · Answer

(A) The given compounds are $p$-nitroaniline,benzylamine,acetanilide,and aniline. Benzylamine is an aliphatic amine,while the others are aromatic amines or amides where the lone pair on nitrogen is involved in resonance or electron-withdrawing effects,making them less basic. Benzylamine is the most basic compound.The molar mass of benzylamine $(C_6H_5CH_2NH_2)$ is $(7 	imes 12) + (9 	imes 1) + 14 = 107 \ g \ mol^{-1}$.Moles of benzylamine in $1.0 \ g = \frac{1.0 \ g}{107 \ g \ mol^{-1}} \approx 0.009346 \ mol$.Benzylamine reacts with $HCl$ in a $1:1$ molar ratio: $C_6H_5CH_2NH_2 + HCl ightarrow C_6H_5CH_2NH_3^+Cl^-$.Moles of $HCl$ consumed $= 0.009346 \ mol$.Mass of $HCl$ consumed $= 0.009346 \ mol 	imes 36.5 \ g \ mol^{-1} \approx 0.3411 \ g$.Converting to $mg$: $0.3411 \ g 	imes 1000 \ mg \ g^{-1} \approx 341 \ mg$.

Given below are some nitrogen-containing compounds. 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 $g \ mol^{-1}$: $C:12, H:1, O:16, Cl:35.5$)
