 Ironically enough, it took me to go to Oregon to find my wife, who's from Virginia. And I'm from South Carolina, you know? So that's really weird, you know? But anyways, so, same problem, right? Bond association energy. Remember, same stability is just like we went over last time. And now we're just comparing these three radicals, same structure, right? It's just less that hydrogen atom or hydrogen radical, whichever you want to think of it. So here we've got a secondary radical, here we've got a tertiary radical, and here we've got a primary radical, right? And remember the radical stability mirrors carbocation stability, right? So, which one of these is the least stable? Yeah, so this is the least, right? And then the most of course is the most stable. Is there any questions on these things before we pretty straight forward, right? I mean, just more physical chemistry. Usually you'll learn this stuff at the end of an organic one, you know?
