delta T = i*Kb*m
i = van't Hoff factor
i = 1 for glucose
i = 2 for KF
Take a look at the formula. For the same m and the same Kb, the only difference is i.
So i*Kb*m must be a greater number for which one. And the greater number for delta T + 100 (the normal boiling point for H2O) means a higher boiling point.
