 Okay, so it looks like we're having a little more trouble taking the name and drawing the compound. The way I would do this, well first we know it's a heptane, so there's seven carbons in it, and it's a bicyclet. So already we know that there's the two bridgehead carbons. That's where I would start. So just maybe two carbons like that, okay? What are we saying? It's bicyclet, but four, one, zero. So there's really only two fused rings here. One of the rings isn't present, right? So what can we say? So let's go zero. So there's going to be just a line between the two bridgeheads. So there's one carbon between the two bridgeheads like that, and then four. So between the two bridgeheads, one, two, three, four, and then we have that. So that's the compound right there. This is bicyclet, four, one, zero, heptane. So let's prove that to ourselves. Just go backwards and figure it out. So bicyclet, yes, there's the rings that have the two bridgehead carbons. Seven, one, two, three, four, five, six, seven. So it's a heptane, right? And then zero carbons in between those two. One carbon in between those two going that way. And then one, two, three, four carbons going that way. Any questions on that one? Did anybody get it right? Without? Yep. Okay, sounds like somebody's the big winner out there. Okay, any other questions? So you're talking about did you draw that one like that? No, like if you were to draw any of it out of the four dots, if you were to draw it in a different way. So you're saying like, I don't know, try to draw it as a chair or something like that? Yeah. You could do that, right? Which way do you draw it? That's the same compound, right? Yeah. Okay. That's an ugly drawing, but. Mindful set that. All that's, you're doing it in a chair structure. Okay, any other questions? Okay.
