Assertion (A): `0.1 M` solution of `NaCl` has greater osmotic pressure than `0.1 M`solution of glucose at same temperature.
Reason (R ): In solution, `NaCl` dissociates to produce more number of particles.

Options

A. If both `(A)` and `(R )` are correct, and `(R )` is the correct explanation of `(A)`.
B. If both `(A)` and `(R )` are correct, but `(R )` is not the correct explanation of `(A)`.
C. If `(A)` is correct, but `(R )` is incorrect.
D. If `(A)` is correct, but `(R )` is correct.

Answer

A

Explanation

For `NaCl`,`i=2`, while for glucose, i=1.Hence, osmotic pressure of `NaCl` is higher than that of glucose solution.
