What are hydrogen bonds?

• Electrostatic interactions between hydrogen and an electronegative atom

• Covalent bonds between hydrogen atoms

• Ionic bonds between hydrogen and oxygen

• Metallic bonds involving hydrogen

What is the main difference between intramolecular and intermolecular forces?
