D) A C B

Question

What is the correct order of boiling points for the following compounds? 
A) A > B > C 
B) C > B > A 
C) B > A > C 
D) A > C > B

Quizplus · Accepted Answer

The order of boiling point is determined by intermolecular forces. Compound B has the highest boiling point because it has the strongest intermolecular force of attraction (ion-dipole interaction) due to the presence of ionic compounds. Compound A has the second highest boiling point because it has hydrogen bonding between molecules. Compound C has the lowest boiling point because it only has London dispersion forces between molecules. Therefore, the correct order is B > A > C. Choice C matches this order.
