The given bonds are silicon oxygen bond, nitrogen oxygen bond, carbon oxygen bond, oxygen bond and finally magnesium oxygen bond.
00:16
The question is which of the given bond is more polar bond? so polar bonds are those in which the bonded atoms have high electronegativity difference.
00:32
So there will be high electronegativity difference.
00:37
So we know that the electron negativity of now value of nitrogen is 3 .04 and silicon is 1 .9.
00:46
Magnetium is 1 .31.
00:50
Carbon is 2 .55 and finally oxygen is 3 .44.
00:57
So the first bond is silicon oxygen bond.
01:00
So here electron negativity of silicon is 1 .9 and oxygen is 3 .4.
01:05
So the electronegativity difference is 1 .54.
01:13
And the second bond is nitrogen oxygen bond.
01:17
So here nitrogen 3 .04.
01:19
So the difference between this will be 0 .4.
01:26
And next one is carbon oxygen bond.
01:29
So the electronegativity difference will be 0 .89.
01:35
And the next one is oxygen, oxygen bond.
01:40
So the electron negativity difference will be 0.
01:44
And the final one is magnesium oxygen bond...
