Vedclass · Answer

(D) The elevation in boiling point is given by $\Delta T_{b} = i 	imes K_{b} 	imes m$. Since the concentration $(m)$ is the same for all solutions,the elevation in boiling point is directly proportional to the van't Hoff factor $(i)$. $(i)$ For $1 \%$ urea,$i = 1$ (non-electrolyte). $(ii)$ For $1 \%$ sucrose,$i = 1$ (non-electrolyte). $(iii)$ For $1 \%$ NaCl,$i = 2$ (dissociates into $Na^{+}$ and $Cl^{-}$). $(iv)$ For $1 \% CaCl_{2}$,$i = 3$ (dissociates into $Ca^{2+}$ and $2Cl^{-}$). Since $CaCl_{2}$ has the highest van't Hoff factor $(i = 3)$,it will show the maximum elevation in boiling point. Therefore,the $1 \% CaCl_{2}$ solution has the highest boiling point.
