Hello students, so the first part of the question is to draw all the possible resonance fluid structure.
00:06
So the first is the n2o, so here the n2o has a structure of n double bond n double bond o.
00:15
So here the charges, the formal charges on the nitrogen, nitrogen and oxygen are, so here it has the zero formal charge, here it has the plus one and here it has the minus one.
00:28
Since the nitrogen has the ability to only, only make three, three bonds, so here it is four, so it has the charge of plus one and here it can make three but it has one charge, so it has two bonds, so it has the charge of minus one, so it has extra of one electron.
00:45
And here the oxygen is unsatisfied.
00:47
Now the resonance structure of this is n triple bond n, the single bond with oxygen.
00:56
So here the oxygen has the minus one charge, here again it has the plus one charge and here it has the neutral charge.
01:05
So among this, so among this the most preferable favoured resonance will be, so here, so the total charge of both the resonating lewis structure is zero, so here there will be none both among them, this both are the stable.
01:27
So now let's move towards the next.
01:30
So i'll write over here, both structure are favourable.
01:39
So this both are favourable.
01:41
Now let's see for the lewis structure of co3 to negative.
01:49
So now let's see the lewis structure of co3 to negative.
01:53
So here we have the carbon as a central item and here double bond oxygen, single bond o with negative charge and here single bond o with negative charge.
02:07
So here as we can see the formal charge on oxygen is negative, negative, here the carbon has the formal charge of zero and here it has the zero.
02:15
So the whole charge is minus two.
02:17
So the resonating structure will be, so here this minus charge will form double bond and this double bond will now go towards the oxygen and will give rise to the single bond oxygen with negative charge and here oxygen with negative charge and here double bond with oxygen...
