Question

On the basis of information given below mark the correct option.

Information

(I) Inbromoethane and chloroethane mixture intermolecular interactions. Of A – A and B – B type are nearly same as A – B type interactions.

(II) In ethanol and acetone mixture A – A or B – B type intermolecular interaction are stronger than A – B type interactions

(III) In chloroform and acetone mixture A – A or B – B type intermolecular interaction are weaker than A – B Type interactions.

• A. Solution (II) and (III) will follow Raoult’s law
• B. Solution (I) will follow Raoult’s law
• C. Solution (II) will show negative deviation from Raoult’s law
• D. Solution (III) will show positive deviation from Raoult’s law.

Answer 1

Answer: (B)

Solution (I) will follow Raoult’s law

Answer 2

Mixture of bromoethane and chloromethane is an ideal solution and will follow Raoult’t law as intermolecular interactions of A – A and B – B type are nearly same as A – B type interactions.
