 Okay, so let's try another one of these bicyclos, so this one's bicyclo 4-3-2 on decking, okay? So remember, the first thing that I like to do is write the bridgehead carbons, okay? So I just write those two like that, okay? So then I like to go 2-3-4, okay? So 2-1-2 to the bridgehead. Is everybody okay with me doing that, okay? Next, 3-1-2. That was an ugly one. 1-2-1-2-3. Back, like that, okay? I told you, it's ugly the first time you try it, okay? And then this one, 4, right? 1-2-3-4. And then back, like that, okay? Any questions on how to do that? So if you're trying to draw it in chair form and stuff like that, yes, you can draw it that way, but it's tough, okay? It's tough. Okay, let's just prove to ourselves that we've done this right, okay? So it's a bi-cycle, hopefully by now everybody can see that, right? Undecaying. So how many carbons this should be? 11. 11. 1-2-3-4-5-6-7-8-9-10-11. So we're good there, right? And now we do, well, we've already done it, but let's just do it for fun. 1-2, 1-2-3, and 1-2-3-4. Are we good? Okay, any questions on that one? Okay, wonderful.
