Excuse me Mr. Laurel, can you go over how Ionic bonds affect melting/boiling points?
Of course!
Ionic bonds typically result in high melting and boiling points because since they have a large number of ions, a lot of energy is needed to overcome the ionic bond, resulting in high boiling and melting points.
They have low boiling and melting points because the attractions between molecules are very easy to overcome. They also don't conduct electricity
What about covalent bonds?
What about hydrogen bonds? Also are hydrogen bonds strong or weak?
Hydrogen bonds also have high boiling and melting points. Also hydrogen bonds are a strong intermolecular force, but are still weaker than ionic and covalent bonds
They are the weakest intermolecular force. When its force decreases, so does its melting and boiling points.
What about London dispersion forces?
What about dipole-dipole forces? Are they strong or weak? How are their boiling/melting points?
Dipole-dipole forces are weak compared to ionic and covalent bonds. Since they are relatively weak, they have low boiling/melting points as well. However if the molecular weight goes up, so does the melting/boiling points.
