NEET Chemistry Raoult's Law Assertion Reason Question
Assertion (A): A solution of ethanol and acetone shows positive deviation from Raoult's law.
Reason (R): The intermolecular forces between ethanol and acetone molecules are stronger than those in pure ethanol.
Both (A) and (R) are true and (R) is the correct explanation of (A).
Both (A) and (R) are true but (R) is not the correct explanation of (A).
(A) is true but (R) is false.
(A) is false.
Correct Answer
Detailed Explanation
The NCERT context explains that ethanol and acetone show positive deviation because acetone disrupts the hydrogen bonding in ethanol, indicating weaker interactions in the mixture than in pure ethanol.
