 Okay. So let's try this one. Is this a bicyclo or a spiral cycle? No. So this is more of just a cycloalkane, okay? So on the cycloalkane, right, we have two portions that are cyclic. How do we know which one is going to be the base of the compound? The larger cycle. The larger of the two, okay? So the larger of the two. So the larger of the two is a what? Cyclohexane, right? Okay. And then what is this thing here? No, cyclobutane, right? So we're going to say that we have a cyclobutane substituent on our cyclohexane, okay? So and it's on the one carbon, right? So we say one cyclobutyl cyclohexane. Any questions? That makes sense? Are there any questions? Yes, no, maybe? You have a question? No questions. Okay, wonderful. Any other no questions or questions? Okay.
