Covalent bonds are formed between atoms which have
- unsatisfied valency
- no inert gas electronic configuration
- These are directional bonds
- formed by sharing of electrons
Intermolecular forces
- much weaker than covalent bond
- These are not directional (except Hydrogen bonds)
- These are more electrostatic in nature
- exist between stable molecules
- can be Hydrogen bonding, dipole-dipole and induced dipole-induced dipole
