Question
The freezing point among the following equimolal aqueous solutions will be highest for

The freezing point among the following equimolal aqueous solutions will be highest for
a. ( C_{6} mathrm{H}_{5} mathrm{NH}_{3} mathrm{Cl} ) (aniline hydrochloride)
b. ( mathrm{Ca}left(mathrm{NO}_{3}right)_{2} )
c. ( mathrm{La}left(mathrm{NO}_{3}right)_{3} )
( mathrm{d} . mathrm{C}_{6} mathrm{H}_{12} mathrm{O}_{6} ) (glucose)
Solution

( C_{6} H_{12} O_{6} ) (glucose)
Glucose being nonelectrolyte produces
lesser value of ( -Delta T_{f} ) and hence higher
freezing point.
