As mentioned in the question, dipole moment it occurs when there is separation of charge.
00:13
When there is separation of charge, dipole moment occurs.
00:21
It arises from difference in electronegativity.
00:30
That is there will be change in the electronegativity.
00:35
There will be change in the direction of dipole moment from positive to the negative.
00:48
Let us consider the atom and the electronegativity.
00:54
Here the atom is let us say it is hydrogen and its electronegativity is 2 .1.
01:05
Fluorine 4, carbon 2 .5, cl 3, lithium 1, bromine, boron 2.
01:29
Let us consider the first one hf.
01:35
H is 2 .1 electronegativity, f is 4 .0.
01:42
Hf, partial positive charge, partial negative charge.
01:54
F is more electronegative than hydrogen.
02:08
So there is partial negative charge on fluorine and partial positive charge on hydrogen.
02:28
This is about the electronegativity dipole moment of the first hf.
02:41
Let us consider the second one that is bc 2 .0, 12 .5...
