Answer 1

Boiling point of solution depend on product of ions formed after dissociation and concentration.

FeI2 give 3 ions thus product is 3×0.17 = 0.51

CaI2 give 3 ions thus product is 3×0.15 = 0.45

Ni(NO3)2 give 3 ions thus product is 3×0.18 = 0.54

Ethylene glycol don't dissociate thus product is 0.48

Hence, answer is

1) FeI2 : B) Second highest boiling point

2) CaI2 : D) Lowest boiling point

3) Ni(NO3)2 : A) Highest boiling point

4) Ethylene glycol : C) Third highest boiling point
