CrashCourse

We’ve already learned a lot about electrophilic aromatic substitution (EAS) and benzene, but guess what? There’s even more to learn! In this episode of Crash Course Organic Chemistry we’ll revisit our old friends the Friedel-Crafts reactions and learn some of their limitations and look at where substitution happens when there are multiple directing groups on a benzene ring. Plus we’ll introduce some benzylic reactions!

In which John Green sings the Crash Course intro song, is interrupted by quite possibly the loudest truck in all existence, and attempts to pronounce the most difficult word in the history of words - which is apparently "misanthropy."

Nearly every environment on Earth — and that includes animals — is home to some kind of parasite. Today we’re going to talk about parasites not just because they’re an essential part of their ecosystems, but also because by studying them we can learn more about their hosts and even their shared evolution and ecology. So stick with us, this one is going to get a little weird!

In which John Green teaches you about the poetry of Sylvia Plath. When a lot of people think about Sylvia Plath, they think about her struggles with mental illness and her eventual suicide. Her actual work can get lost in the shuffle a bit, so this video really tries to focus on the poetry. You'll learn about Sylvia Plath's role as a feminist poet, and you'll also learn about her extraordinary ability to recreate the experiences of real life in a beautiful and relatable way.
