Whenever we add solid solute to a liquid solvent it's freezing point decrease which is called Freezing point depression.
Freezing point depression is a colligative property which depend on moles of solute particles.
∆Tf=iKf.m where Kf is constant. So the value of Freezing point depression depend on product of i(vant hoff factor) and m(molality).
So order of Freezing point would be:-(lowest to highest)aq MgI2(i×m=0.66) aq NaF(i×m=0.62), aq glucose (i×m=0.6), aq sucrose (i×m=0.5), H2O
