What is the difference between #"intermolecular"# and #"intramolecular force"#?
Well, the one is a measure of
........and t'other is a measure of the
Well, the boiling point reflect the strength of interaction BETWEEN molecules of dihydrogen, where only weak dispersion forces operate. On the other hand the bond strength measures the degree of INTRAMOLECULAR interaction, the bond between the hydrogen atoms in a discrete hydrogen molecule.
For another example of INTER versus INTRAMOLECULAR FORCE consider the bond strength of
This distinction between intermolecular and intramolecular force has been recognized as a problem area of A level and 1st year university chemistry, and I urge you to read the appropriate chapter of your text that addresses the issue.
intramolecular forces are the bonding of atoms that holds a molecules together intermolecular forces hold molecules together in a solid or liquid.
Using water as an example
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.
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.
