|Intermolecular forces||Intramolecular forces|
|Intermolecular forces are the forces present between atoms of two different molecules||Intramolecular forces are the forces present between the atoms of the same molecule.|
|Forces between two molecules||Forces within a molecule|
|Weaker forces||Stronger forces|
|In these forces, molecules are suspended and gripped in a substance.||In these forces, atoms are gripped in a molecule.|
|Physical parameters such as melting points, boiling points and physical states such as solid, liquid or gas are determined by such forces.||Chemical parameters such as the reactivity, the flammability or susceptibility to corrosion etc of a substance are determined by such forces.|
|These forces are classified into: |
Ion dipole forces, Ion induced dipole forces, Dipole-induced dipole forces, dipole-dipole forces including Hydrogen bonding and London dispersion forces.
|These forces are classified into:|
Ionic Bond, Covalent Bond and Metallic Bond.
|These are sometimes named as nonbonding forces.||These are sometimes named as bonding forces.|
|Persist for shorter life span of molecule||Persist for longer life span of molecule|
|Physical changes can affect such forces.||Physical changes cannot affect such forces usually.|
|Liable to bulk properties of matter||Liable to stabilize the molecule|
|Intermolecular bond distance can be longer||Intramolecular bond length is shorter.|
