To draw the appropriate lewis structure for h2c2n, we first need to calculate the total number of valence electrons.
00:13
Hydrogen has one, there are two of them.
00:16
Carbon has four, there are two of them.
00:20
Nitrogen has five, there's one of them.
00:23
And then we have an extra one electron from the negative charge.
00:28
This gives us a total of 16 valence electrons.
00:32
Then we need to figure out the structure of h2, c2n.
00:39
So it's likely going to be a carbon bonded to two hydrogens, bonded to another carbon, and then bonded to a nitrogen.
00:47
This would have used up to four, six, eight, half of the 16 valence electrons.
00:56
If we add two more right here, that'll give this carbon an octet.
01:04
If we add two more here, that'll give this carbon an octet...
