Are intermolecular forces between two molecules or the forces within a molecule? Wiki says that they are forces between two molecules.

So between NH3 and HCl, the intermolecular forces would be dispersion? I always thought that intermolecular forces were within a molecule. Like in a water molecule, the intermolecular forces are H-bonding.

Wiki is right. Forces between molecules, hence "inter"molecular forces. H-bonding is intermolecular, it's between Hydrogen (positive) of one molecule and oxygen(electronegative) of another molecule.

intermolecular = between 2 molecules
intramolecular = within molecule

I believe H2O has both intermolecular & intramolecular hydrogen bonding (correct me if I am wrong)

Also NH3 & HCl has intermolecular hydrogen bonding between them.

How is NH3 and HCl even bonded 2gether? im confuzleddd 😕

and I think intramolecularly H20 is covalently bond only and intermolecularly, water molecules are bond via H bonding...

Also, for intermolecular, think INTERstate highway (between 2 separate states)...that always clears it up for me.

so if intermolecular forces include H bonding and van der waals (dipole-dipole and dispersion)..wat exactly are electrostatic forces and where do they fit into the scheme of this whole intermolecular/intramolecular force business?😀

electrostatic forces are between 2 charged molecules, so they would be classified as intermolecular forces.
