Solving problem 26 of chapter 15.
00:07
Penitrine as five resonant structures, one of which is shown, draw the other four.
00:13
So let's start with the one structure that is reported in the book.
00:30
Let's put the double bonds.
00:32
One in here.
00:33
One in here.
00:35
One in here.
00:42
Here.
00:43
And we'll be here.
00:47
Now let's start moving electrons around.
00:50
This one can go here, this one here, this one here.
00:55
And let's rewrite down the corresponding structure.
01:08
So we move this double bond now is here.
01:12
This one from here it goes here.
01:15
And this one from here, it goes here.
01:18
The other double bonds remain as they were.
01:25
Now we can do the same on this side.
01:30
So let's start from this one goes here...
