In this problem, we're given a cat .m.
00:05
And we're asked to draw curved arrows to move double bonds or loan pairs to get different resonant structures.
00:13
So we're going to do that first.
00:17
And remember that oxygen has extra loan pairs.
00:21
So we could drop a pair in here.
00:23
Now, the problem is this carbon can't have five bonds.
00:27
So electrons for this bond can come over here.
00:31
But now this carbon can't have that many bonds.
00:35
So these electrons drop onto nitrogen.
00:40
So now we have a lone pair there, and it looks like this.
00:48
And remember our overall charge has to be the same.
00:52
So if we look at oxygen, it has six balanced electrons.
00:56
You subtract the number of bonds and the number of one electrons.
01:00
We get plus one.
01:02
And because you had plus one over here, you're going to have plus one down there.
01:06
So that's where it's going to be...
