Vedclass · Answer

(C) The elevation in boiling point is a colligative property,which depends on the van't Hoff factor $(i)$.$i$ for $NaCl$ is $2$ $(Na^+ + Cl^-)$.$i$ for sucrose is $1$ (non-electrolyte).$i$ for $BaCl_2$ is $3$ $(Ba^{2+} + 2Cl^-)$.$i$ for glucose is $1$ (non-electrolyte).Since $BaCl_2$ has the highest van't Hoff factor,it will produce the maximum number of ions in the solution,leading to the highest elevation in boiling point.

Which of the following will have the highest boiling point at $1 \ atm$ pressure?
