Which statement is true about the solution of chloroform and acetone ?

Options

A. The solution formed is ideal
B. A non-ideal solution with positive deviation
C. A non-ideal solution with negative deviation
D. Unpredictable

Answer

C

Explanation

The interparicle forces between acetone and chloroform are H-bonds which are stronger than those between acetone molecules or chloroform molecules separately. As such the vapour pressure of solution is less than expected and the solution shows a negative deviation.
