E-z notation Memes

Organic chemistry professors really woke up and chose violence with E/Z isomerism. The exact same molecule can be labeled completely opposite ways depending on which side you're looking from! It's like naming your dog "Fluffy" when you're standing in front of him and "Not Fluffy" when you're behind him. The real chemistry lesson here is that perspective matters—unless you're taking an exam, then only the professor's perspective matters. Suddenly those stereochemistry questions on exams feel like a personal attack.
