A mixture of phenol and aniline shows:
ANegative deviation
BPositive deviation
CIdeal behaviour
DZero solubility
Answer & Solution
Correct answer: A. Negative deviation
1. Hydrogen bonding forms between the phenol proton and the nitrogen.
2. That bond is stronger than the bonds within each pure liquid.
3. So the mixture shows a negative deviation.
