The structure that they've given us looks like this, where we have two carbons bonded to each other, and then off of each carbon, we have another carbon, and off of each of those, we have a nitrogen.
00:16
So first we'll count the total number of valence electrons.
00:20
The chemical formula is going to be c6n4.
00:27
Carbon has four valence electrons.
00:29
There are six of them.
00:31
Nitrogen has 5 and there are 4 of them.
00:35
This gives us the total of 44 valence electrons.
00:40
We already see in the structure 2, 4, 6, 8, 10, 12, 14, 16, 18.
00:49
Having used up 18, we then have a remaining 26...
