 Okay, we'll try this one. What type of step is this one? It's a propagation step, right? Because you only got initiation, propagation, and termination to choose from. So it's a propagation step. Have you guys done the mechanism before again? No. Why not? Start writing. So what's happening here? If you are having a hard time, what I would do is one, two, three, four. So the radical is on that fourth carbon now, right? You see that? So what's happening? So what's happening? So it's easy to see, right? It's easy to see, but I guarantee you if you don't know how to do it, start trying to draw this on a test without ever drawing it before. You get confused, okay? So it seems a lot easier than what it is. I would label my carbons, okay? Especially if I were in your shoes. Are there any questions about this one? Oh, yes. What is it called again? Elimination. Yeah, this is an elimination, right? So you're eliminating this piece here. So it's a type of propagation. Why? Because we've got one radical. I think all of these in this problem are type of Oh, is there a termination? Yeah, and there's an initiation step too. So yeah, C is the termination and F is an initiation. Nobody needs us to go.
