Boiling Point

Postby ayushibanerjee06 » Wed Nov 20, 2019 3:12 pm

Which one has a higher boiling point: SO2 or O3?

O3 should have a higher boiling point because the bond between oxygen-oxygen is stronger than the bond between oxygen and sulfur. This is because the oxygen molecule has a smaller diameter than the sulfur atom due to having one less shell of electrons. This allows the bonding electrons to revolve closer to the nuclei of the oxygen atoms versus the nucleus of the sulfur atom.

I think SO2 would have a higher boiling point because it has more electrons than O3, therefore making it more polarizable. Since it is more polarizable, it has stronger van der waals forces, which take more energy to break, causing SO2 to have a higher boiling point.

I agree that SO2 would have the higher boiling point for the reasons above. Intermolecular forces are what is important in this instance, not intramolecular bonds.

SO2 would have the higher boiling point because S has more electrons making it have higher attractive forces making the dipole-dipole interactions stronger in SO2 than in O3

if something had hydrogen bonding, it would have a high boiling point correct?

what is an acceptable justification to the question--why does X compound have a higher boiling point?

Yes it’s the second strongest bond after ionic bonding
