What are the intermolecular forces that are present in all molecules? let us consider the intermolecular forces that are mentioned in the question and identify them that are present in all molecules.
00:20
If we consider first one that is hydrogen bonding.
00:24
Hydrogen bonding is formed between a hydrogen atom and an electronegative element.
00:34
This electronegative element may be nitrogen, oxygen, chlorine, fluorine.
00:47
Next we have dipole -dipole interaction.
00:53
Dipole -dipole interaction is formed when a molecule possess polarity.
01:00
In dipole -dipole interaction, one molecule possess, one molecule is polar.
01:10
When a molecule is polar, that is one molecule is polar molecule.
01:18
And this polar molecule is attracted to the opposite polar side of another molecule.
01:32
That is negative attracts positive.
01:38
Negative poles attract positive, positive poles attract negative poles.
01:46
And these poles are generated because of electronegative difference between 0 .4 to 1 .7.
02:03
Poles are generated because of this electronegative difference.
02:08
And when these poles interact with each other, dipole -dipole interaction occurs.
02:15
Next we have ion -ion interaction.
02:19
An ionic bond, ion -ion interaction indicates an ionic bond is formed between opposite charges ions.
02:34
Between oppositely charged ions, ionic bond is formed...
