b.Boiling point of Y <X
c.Freezing point of Y<X
d.Both have same vapour pressure

Answer:

OPTION C IS THE CORRECT ANSWER. PLZ MARK ME AS BRAINLIEST ANSWER.

Answer 2

The correct relation about the aqueous solution of 0.1 M NaCl (X) and 0.2 M MgCl2 (Y) is:

(c) The freezing point of Y<X

- As the molarity for MgCl2 (Y) is more than NaCl (X), all the colligative properties will be more for it.

- It means that option (a) is wrong as the osmotic pressure will be more for Y.

- The option (b) is also wrong as the elevation in boiling point will be more for Y.

- The option (c) is correct as the depression in the freezing point will be more for Y and hence its freezing point will be less than X.

- The option (d) is also wrong as the vapour pressure will not be the same due to difference in concentration.
