Chemistry · PYQ NEET UG 2026
हिन्दीAssertion (A): For an ideal solution formed by mixing liquids P and Q, \( \Delta_{\text{mix}} \text{H} = 0 \) and \( \Delta_{\text{mix}} \text{V} = 0 \). Reason (R): No interactions occur between P and Q. In the light of the above statements, choose the most appropriate answer from the options given below.
Correct answer · Option 3
A is correct but R is not correct
Explanation
For an ideal solution, \( \Delta_{\text{mix}}H = 0 \) and \( \Delta_{\text{mix}}V = 0 \) because solute-solute, solvent-solvent and solute-solvent interactions are nearly identical (not non-existent). Hence, reason is incorrect.
