Question

Mixing of acetone with chloroform takes place with a reduction in volume. What type of deviation from Raoult's law is shown in this case?

Answer 1

This negative deviation between the intermolecular force of attraction between the molecules of acetone and chloroform is much stronger which result in a decrease in volume of the solution as well as the tendency of the molecule to escape from the liquid due to which vapour pressure of the solution decreases.
