Hello.
00:02
Here we are given a molecule pharma, c2 and 3 negative and we have to draw the huge structure and assign with formal charge.
00:13
Firstly think about there is three nitrogen and two carbon.
00:17
There is no hydrogen so there must be a side night in this structure.
00:24
So by hit and trial method we can assign a structure like this.
00:30
Way there is cyanide group and other cyanide group is here this is the formula for this structure and this there is one two and three nitrogen and two carbon and the negative charge here because nitrosins are satisfied without this negative charge so this is the required formula for the required structure for the molecular form so so we are going to assign formal charge.
01:08
Firstly, this nitrogen, this nitrogen has a formal charge of minus 3 and this carbon is one charge of plus 4 because it mounted to 3 nitrogen tripletely pointed and one want this and this is low electronegativity, less electronegativity as compared to nitrogen.
01:26
So it is formal charge of plus 4.
01:27
We can say oxidation state is plus 4 and here is a minus 3 oxidation state of nitrogen and and here also same plus 4, 6 .6 and formal charge we can say that and minus 3.
01:40
And for this night notion, please be remember that it is real charge, not formal one...
