Vedclass · Answer

(C) The boiling point elevation is a colligative property,which depends on the van't Hoff factor $(i)$ of the solute. The formula is $\Delta T_b = i 	imes K_b 	imes m$. Since the molality $(m)$ is the same for all solutions,the solution with the highest van't Hoff factor $(i)$ will have the highest boiling point. $1.$ $KNO_3 ightarrow K^+ + NO_3^-$,$i = 2$. $2.$ $	ext{Urea}$ is a non-electrolyte,$i = 1$. $3.$ $K_4[Fe(CN)_6] ightarrow 4K^+ + [Fe(CN)_6]^{4-}$,$i = 5$. $4.$ $NH_4NO_3 ightarrow NH_4^+ + NO_3^-$,$i = 2$. Comparing the values,$K_4[Fe(CN)_6]$ has the highest $i$ value $(i = 5)$,therefore it has the highest boiling point.
