Question

Which is the correct option at same temperature for 1 %

w/v aqueous solutions of Urea, Glucose and Sugar?

[Molecular Mass : Urea=60 u, Glucose=180 u, Sugar=342 u]

(A) Π Urea = Π Glucose = Π Sugar

(B) Π Urea > Π Glucose > Π Sugar

(C) Π Urea > Π Sugar > Π Glucose

(D) Π Sugar > Π Glucose > Π Urea​

Answer 1

Answer:

(A) Π Urea = Π Glucose = Π Sugar

Explanation:

As urea , glucose and sugar are non ionic substance they do not dissociate in the solution so their degree of ionisation is same.

Therefore their osmotic pressure is same.
