Here the question is to find which of the following bond is least polar, but yet still be considered as polar covalent bond.
00:12
Now what is a polar covalent bond? it is a covalent bond in which consider a bond between a and b, and if there is a large electronegativity difference.
00:24
That means if a is highly electronegative, then the a is having a tendency to attract the shared pair of elements.
00:31
Towards itself and the electron cloud around the atom or we can say the electron cloud which is present in between the atom will be shifted towards the side because as i said earlier a is more electronegative.
00:50
So then what happens is electron cloud will be shifted towards like this.
00:56
This is a and this is b and there will be a partial negative charge here and a partial positive charge, which means there is a creation of a polarity and that is what is a polar covalent bond.
01:12
That means if the electronegativity difference between these two atoms, let's say a and b, is more, then the polarity will also will be higher.
01:25
That means the electronegativity difference is higher, it's higher than polarity.
01:34
Will also be higher.
01:37
And if it is lower then we will say it is less polar.
01:43
Now electron negativity is the tendency of the atom to attract the electron pair towards itself.
01:54
So we will see the electronegativity of each atom.
01:58
So this both shows polling scale electro negativity values of these elements and we will see each option.
02:05
First one is m -g -o.

Now, muthnisham is electropositive and oxygen is having 3 .5 which means this is a highly polar covalent bond...
