Question: Which of the following has the highest freezing point?...

Which of the following has the highest freezing point?

A

1 m NaCl solution

B

1 m KCl solution

C

1 m AlCl3AlCl_{3} solution

D

1mC6H12O61mC_{6}H_{12}O_{6}Solution

Answer

1mC6H12O61mC_{6}H_{12}O_{6}Solution

Explanation

Solution

C6H12O6C_{6}H_{12}O_{6} is a non electrolyte hence furnishes minimum number of particles and will have maximum freezing point.
