Question

Identify the correct order of boiling points of the following compounds

(a) A > B > C

(b) C > A > B

(c) A > C > B

(d) c > B > A

Answer 1

Correct option (b) C > A > B

Explanation:

In these C forms dimer due to hydrogen bonds and compound A, form hydrogen bonds. Hence, in these stronger hydrogen bond is in compound C than compound A. Compound B does not form hydrogen bond. 

Thus, they follow the following order of mol. wt. C > A > B. So, they have same order in their boiling point.
