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

Options

A. `C_(6)H_(5)NH_(3)Cl`(aniline hydrochloride)
B. `Ca(NO_(3))_(2)`
C. `La(NO_(3))_(3)`
D. `C_(6)H_(12)O_(6)`(glucose)

Answer

D

Explanation

`C_(6)H_(5)NH_(3)Cl rarr C_(6)H_(5)NH_(3)^(o+)+Cl^(ө)`
`Ca(NO_(3))_(2) rarr Ca^(2+) + 2NO_(3)^(ө)`
`La(NO_(3))_(3) rarr La^(3+) + 3NO_(3)^(ө)`
Glucose does not dissociate. So it has the minimum number of particles, and therefore, it shows minimum depression in freezing point. So it has the maximum freezing point.
