Question

On the basis of information given below mark the correct
option.
Information
(i) In bromoethane 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 interactions are stronger than A — B
type interactions.
(iii) In chloroform and acetone mixture A — A or B — B
type intermolecular interactions 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:

solution 1 will follow Raoult's law because the solution formed after mixing will be ideal and do not show any deviation as the intermolecular forces after mixing are same so the answer is (b)

Answer 2

Answer : the answer is option b
