First of all, let's have a look what all is given in the problem.
00:06
Given is some of the compounds are given like o3.
00:13
Second one is so2 and the last one that is given is no2 minus.
00:21
No2 minus.
00:23
What we are supposed to find out, we have to draw all the resonating structures and find the formal charge on it.
00:33
Structures with formal charge on all the atoms.
00:39
So this we are supposed to do.
00:43
First of all, let's do for the ozone.
00:46
Let's draw the resonating structure for ozone, that is o3.
00:54
One of the structure for ozone will be this.
00:59
This will have minus charge and this will have plus charge and one loan pair will be present.
01:06
Similarly, the other resonating structure will be this.
01:14
Again, positive charge with loan pair and this will have negative charge.
01:20
So this is the structure.
01:22
Now let's label the, let's label the carbon atom, oxygen atoms also.
01:32
This will be first, second and third.
01:34
And for this, a, b and c.
01:37
Let's calculate the formal charges.
01:41
For o1, the number of aliens electron is vat 6 and number of n.
01:47
Number of non -bonding electrons are 4 minus bonding electrons by 2.
01:53
So it will come 0.
01:56
On 0, 2, it will be 6 minus 2 minus 6 by 2.
02:00
So it will be plus 1.
02:02
And then 0 3, it will be 6 minus 6 minus 2 by 2.
02:06
That means minus 1.
02:09
Similarly, we can calculate the charges on this also.
02:13
Oa, ob and oc.
02:16
Oa will be 6 minus 6 minus 2 by 2 that means minus 1 ob will be 6 minus 2 minus 6 by 2 that means plus 1 and oc will be 6 minus 4 minus 4 by 2 that means 0 so these are the formal charges now let's draw for the second one that is so2 let's draw the resonating structures first the resonating structures will look like this this is the first resonating structure.
02:50
Two lone pairs are present in oxygen atom and one on sulfur atom.
02:55
Its resonating structure will be oxygen double bonded to sulfur.
03:04
This will be the another resonating structure...
