Question

Please chose the reason form the given 4 in window, and rate the boiling point from 1,2,3,4:

ist the following substances in order of increasing normal boiling points Tb, and explain your reasoning: O2. OF2. H20. Cao Boiling point owest 4 - highest substance Reason 02 O, Is an ionic compound: forces are stronger than forces between neutral molecules. Has hydrogen bonds: stronger than other dipole-dipole interactions. OF2 Is polar: dipole-dipole forces are stronger than dispersion forces. Is nonpolar: dispersion forces are weaker than dipole-dipole forces CaO Submit Answer Try Another Version 5 item attempts remaining

Explanation / Answer

1. Answer

O2- Boiling point 1(Least) Is nonpolar: dispersion forces are weaker than dipole-dipole forces.

OF2 Boiling point 2(second least) : Is polar:  dipole-dipole forces.are stronger than dispersion forces.

H2O Boiling point(3)- Has hydrogen bonds :stronger than other dipole-dipole interactions

CaO Boiling point (4) Highest - Is an ionic compound: forces are stronger than forces between neutral molecules
