You may know that cows produce methane, which is a big concern when it comes to global heating, but did you know that organic chemistry provides a potential solution to this problem? Feeding cows small amounts of red seaweed can greatly reduce methane emissions, in part due to organic chemicals called enols! In this episode of Crash Course Organic Chemistry, we’ll learn all about enols and enolates, their reactivity, and reactions we can do with them including halogenation and alkylation.
