Carbon-carbon double bonds are pretty common in nature, but triple bonds between carbons, called alkynes, are not. When alkynes do pop up in nature, it’s usually in a compound that’s toxic to humans, however, we can synthesize alkynes that are life saving medicines and materials. In this episode of Crash Course Organic Chemistry, we’ll learn about alkynes and some of the reactions we can use them in (hint: it’s a lot of the same reactions we used for alkenes!)
