Diethyl malonate Memes

The molecular structure shown is diethyl malonate, which chemists lovingly nickname "Michael" because it's the key reagent in the Michael addition reaction! The punchline "My name is Michael and I am a crab" is chemistry gold - it's referencing how this molecule participates in 1,4-addition reactions (also called conjugate additions) where nucleophiles attack like a crab from the side rather than head-on. Every organic chemist who's survived synthesis lab is currently having flashbacks to drawing those curved arrows on their exams!
