Question
When 0.1 M aqueous solutions of aluminum nitrate, magnesium nitrate, sodium nitrate and urea, (NH2)2CO, are arranged in order of increasing boiling point, which order is correct?
A.
Al(NO3)3 = Mg(NO3)2 = (NH2)2CO = NaNO3
B.
Mg(NO3)2 < (NH2)2CO < NaNO3 < Al(NO3)3
C.✓ Correct
(NH2)2CO < NaNO3 < Mg(NO3)2 < Al(NO3)3
D.
NaNO3 < Mg(NO3)2 < Al(NO3)3 < (NH2)2CO
