Question
Considering the formation, breaking and strength of hydrogen bond, predict which of the following mixtures will show a positive deviation from Raoult’s law?
Options
Methanol and acetone
Chloroform and acetone
Nitric acid and water
Phenol and aniline
Advertisements
Solution
Methanol and acetone
Explanation:
Mixture of Methanol and acetone shows positive deviation because methanol-methanol and acetone-acetone interactions are more than methanol-acetone. The more number of hydrogen bonds are broken the less number of new H-bonds are formed.
