Okay, we need to draw resonance structures.
00:03
Here's the first molecule.
00:12
Now, what i'll point out is that whenever you've got a carbocadion and you want to draw resonant structures for it, you're going to draw arrows coming from either lone pairs or from bonds, and you're going to draw them towards that carbocation, right? we're drawing something towards the carbocation.
00:32
So here's the resident structure.
00:34
And then we basically just swap places with the carbocation.
00:45
Carbocadine should always move two carbons away.
00:47
One, two.
00:50
Okay.
00:52
Now, the other example we have here involves a carb anion or a negative charge, right? and when we have negative charges, we're going to start from where we have the negative charge, typically when drawing resident structures, right? and then we're going to end up putting usually a loan pair or a negative charge on a different atom.
01:17
So we're going to turn the single bond into a double bond using that loan pair...
