Question
On the basis of information given below mark the correct option.
(A) In bromoethane and chloroethane mixture intermolecular interactions of A–A and B–B type are nearly same as A–B type interactions.
(B) In ethanol and acetone mixture A–A or B–B type intermolecular interactions are stronger than A–B type interactions.
(C) In chloroform and acetone mixture A–A or B–B type intermolecular interactions are weaker than A–B type interactions.
Options
Solution (B) and (C) will follow Raoult’s law.
Solution (A) will follow Raoult’s law.
Solution (B) will show negative deviation from Raoult’s law.
Solution (C) will show positive deviation from Raoult’s law.
Solution
Solution (A) will follow Raoult’s law.
Explanation:
Solution A will follow Raoult’s law due to nearly same interactions between A-A, B-B and A-B. The solution formed will be nearly ideal.
