Question

What is the difference between intramolecular force and intermolecular force?

Answer 1

intramolecular forces are the bonding of atoms that holds a molecules together intermolecular forces hold molecules together in a solid or liquid.
Explanation:
Using water as an example
Intramolecular forces
The bonds between hydrogen and oxygen hold the water molecule together. The sharing of electron density creates a bond that holds the two atoms together.
Intermolecular forces
So called Hydrogen bonding. The difference between the electro negativity between hydrogen and oxygen creates a positive charge on Hydrogen and a negative charge on Oxygfen. The negative charge attracts the Hydrogen on a neighboring molecule. This helps to hold the water molecules together.
Intramolecular forces hold atoms together to form molecules.
Intermolecular forces hold molecules together to form solids and liquids.
