Insects can communicate with each other about all kinds of things, but instead of using words, they use… you guessed it! Organic Chemistry! Insects can send signals to each other by secreting compounds, and one such compound used by termites contains the functional group we’re going to learn all about in this episode: enones! In this episode of Crash Course Organic Chemistry, we’ll learn about crossed aldol reactions, the formation of kinetic and thermodynamic enolates, hard and soft nucleophiles, conjugate addition, and of course, enones!
