Distinguish between intermolecular and intramolecular forces of attraction. Then using NH3 discuss the inter?

and intra molecular forces in the liquid phase of this pure substance.



someone please explain the second part, I know the difference between intra and inter.Distinguish between intermolecular and intramolecular forces of attraction. Then using NH3 discuss the inter?"Intra" means "within", and so intramolecular forces refer to the covalent bonds in NH3. Intermolecular forces refer to the attractions between molecules. In ammonia we find hydrogen bonding, dipole-dipole attraction and London dispersion forces. Of the three, hydrogen bonding is the strongest in ammonia.

All molecules have London dispersion forces, even if other forces are present. Since NH3 is asymmetrical, it is polar, and exhibits dipole-dipole attraction. In addition, we have H internally bonded to N and so hydrogen bonding exists between the H of one molecules and the N of an adjacent molecule.
