Assertion Acetone-Carbon disulphide solution shows positive deviation from Raoul
Assertion Acetone-Carbon disulphide solution shows positive deviation from Raoult's law. Reason Acetone \( + \) Aniline solution shows positive deviation from Raoult's law.
- A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
- B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
- C. Assertion is correct but Reason is incorrect
- D. Both Assertion and Reason are incorrect
Step-by-step solution
Assertion (Acetone-Carbon disulphide) shows positive deviation due to weaker interactions between unlike molecules (dipole-induced dipole). Reason (Acetone-Aniline) actually shows negative deviation due to hydrogen bonding (N-H···O=C), making the Reason false.
