The answer for the first molecule is six. Because I've got to from this double bond I've got to from this told wind, I've also got another two from this old bond. And I've got zero from this cat Ion. You add it all together and you get six pie electrons. Easy move onto the next one.

The answer for this next one was 10 pie electrons because I've got to to to to to that equals 10 pie electrons. Too easy. Let's move on to the next one.

The answer for this next compound was four pi electrons because I had two electrons coming from my double bond. And then I had another two coming from my and I on which he said contributed to pie electrons as well. That would give us four pi electrons total. All right, now, in orderto answer the next three questions, we're gonna have to get a handle on this tricky notation. So if you see a hydrocarbon ring with just a charge in the middle, that means you've got a lazy, organic chemists on your hands. But, hey, this is an acceptable notation, and you do lead to learn what it means. Basically, if you just see a charge in middle, that means that we're gonna assume so I'm just gonna put here. By definition, this means that we're gonna assume alternating double bonds and then the space left over or the carbon left over the Adam left over would possess that charge. So that means that this molecule that five in the ring is actually a shortcut or a shorthand for a five carbon dying with a positive charge on one carbon. So that being said, go ahead and try to figure out how many pilots runs that has, and then use that information to then draw the correct structures of the following two so that you can get the right answers for those as well. You got this.

All right. So the correct answer for this one was for now that we know how to draw it. Because you had 22 and zero giving us a total of four pi electrons. Go ahead and try the next one.

so the correct structure of this molecule was a triangle with simply one double bond and a negative charge in the space afterwards. Because there was Onley enough space for one told one total. This means that this molecule would have a total of four pi electrons. Let's move on to the last question.

The answer for this last one was eight pi electrons. How do we get the answer? Because the negative charge in the middle of meant that we had to assume double bond double bond, double bond with a negative charge here. I could just cross that out, and we would get eight pi electrons from the three double bonds and the anti in which you could contribute Electron seven and eight. So this would be eight pi electrons total. Okay, Now I know that you're not really completely sure how important this pie electron thing is, but it's a huge deal when we're talking about are electricity. So now that you know how to count them, let's go ahead and figure out why they're going to be so important for our electricity.
