Of a covalent bond just allows our non -metals to obey the octet rule and become more stable as a result.
00:05
Here we're looking to draw out a lower structure where we have carbon, nitrogen and oxygen involved.
00:10
So we can look at the total valence electron count.
00:15
So for carbon, we have four electrons, for nitrogen, we have five electrons, for oxygen, we have six electrons, for the formal charges, we have one.
00:31
So we add those up, we get 16, valent electrons to work with.
00:36
So the central atom we know is nitrogen.
00:39
So what we can have is c, n, o.
00:46
So we can have structure one, c n, o, structure two, c, n, single bond, o.
01:07
So we've got structure one, structure 2 and structures 3.
01:19
So we need to account for our lone pairs of electrons.
01:24
So here we have the following with a formal negative charge.
01:34
And again, one formal negative charge overall...
