Answer:
1) intra molecular forces
2) within
3) inter molecular
4) between
Explanation:
In image below black lines indicate the intra molecular forces that exist within molecules and the red dotted lines indicate the inter molecular forces that exist between the molecules.
1) intra molecular forces
2) within
3) inter molecular
4) between
Inter molecular forces:
Inter molecular forces exist between the molecules.
Intramolecular forces:
Intramolecular forces exist between the bonded atoms with in same molecule.
