The luce structure when each atom completed octate would be somewhat like this.
00:05
We will have oxygen, then chlorine and oxygen.
00:08
And since octet is complete, so we have 7 valence electrons for oxygen in this fashion.
00:15
It will be having.
00:19
Here there will be two.
00:20
Here there is two.
00:21
So here what will happen is this is going to complete it octate in this manner.
00:27
So chlorine has completed octet and oxygen has also completed the octet.
00:31
So we can say that loose structure with the whole, each atom is completed octet so formal charge formal charge so even this part is there so even this electron is being considered of the oxygen now the octet is complete completely so formal charge calculation we will do in this part chlorine the valence electron minus non -bonding electrons minus half the bonding electrons this is the formula for calculation of formal charge so if in the case of chlorine, the valence electron is 7, non -bonding electrons over here is 4 minus half times the bonding electrons, that is 2, that is going to come out to be equal to 7 minus 5 which is equal to, whereas in the case of oxygen it is going to be valence electrons is 6, number of bonding electrons is 1 and non -bonding electron is 6.
01:33
So 6 minus 6 minus 1 times 1 is equal to minus 1.
01:37
So, this is the formal charges.
01:40
Moving forward to the b part when expanded octet is there.
01:44
Expanded octet.
01:47
So the loose structure will be cl.
01:52
We will have total 8 electrons, then oxygen in this fashion, and here we will have oxygen over here.
02:04
So this is going to form like this...
