Question

When attraction between $A-B$ is more than that of $A-A$ and $B-B$, the solution will show

• A. positive deviation from Raoult's law
• B. negative deviation from Raoult's law
• C. no deviation from Raoult's law
• D. Cannot be predicted

Answer 1

Answer: (B)

When $A-B$ attractions are greater than $A-A$ and $B-B$, then less vapours are formed and hence, solution shows negative deviation.
