On the basis of information given below mark the correct option. Information: (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.

Question

Philoid · Accepted Answer

Solution A will follow Raoult's law as it is an ideal solution. The intermolecular interactions of A–A and B–B type are nearly same as A–B type interactions.

Solution B will form a minimum boiling azeotrope and show a positive deviation from Raoult’s law.

Solution C will form a maximum boiling azeotrope and show a negative deviation from Raoult’s law.

Thus, Option(ii) is the correct answer.
