Pericyclic reactions Memes

Chemistry puns that physically hurt! This diagram shows the conversion of Dewar benzene to either regular benzene or "argh" through disrotatory or conrotatory ring opening. The joke is that "argh" isn't a real molecule—it's just the sound you make when organic chemistry causes you pain. The title's "pericycle" reference is a clever nod to pericyclic reactions, which is exactly what's happening in these transformations. It's like the molecule itself is screaming in agony during its structural rearrangement. Only chemists would turn molecular suffering into humor.
