Umbrella Memes

Regular people see a broken umbrella and think "bad weather." Chemistry students see the holy grail of nucleophilic substitution mechanisms in the wild! The SN2 reaction (or Walden inversion) is exactly like that umbrella flipping inside out—the nucleophile attacks from the back, the leaving group exits, and boom—complete inversion of stereochemistry. Nothing gets a chemistry major more excited than seeing their textbook reactions manifested in everyday objects. Next time you're caught in a storm, remember: you're not getting wet, you're witnessing molecular orbital theory in action!
