Assertion (A): The osmotic pressure of `0.1 M` urea solution is less than `0.1 M NaCl` solution.
Reason (R ): Osmotic pressure is not a colligative property.

Options

A. Assertion and reason both are correct statements and reason is correct explanation for assertions.
B. Assertion and reason both are correct statements but reason is not correct explanation for assertion.
C. Assertion is correct statement but reason is wrong statement.
D. Assertion is wrong statement but reason is correct statement.

Answer

C

Explanation

Correct reason : NaCl is an electrolyte and two ions. Therefore , osmotic pressure of 0.1 M NaCl is almost double than that of 0.1 M urea solution.
