The One Mental Model That Unlocks OChem Chirality Forever!

Chirality is the stereochemistry idea upon which most of organic chemistry is based - and most students discount it at first. In this video, you’ll see why a carbon with four different groups can only produce two unique 3D versions (not 8, not 16). If stereochemistry feels like memorizing rules, this is your reset. We’ll build the logic from tetrahedral geometry and a simple thought experiment so you can trust what you’re doing on exams. In this video, you’ll learn: 💎 Why sp³ carbon is tetrahedral, not flat 💎 What wedge/dash bonds actually mean in 3D 💎 Why rotation does not create a new molecule 💎 The exact moment the “choice” becomes real (and locks in the last group) 💎 What a chiral center is (4 unique groups) 💎 Why the two versions are enantiomers (not superimposable) Quick check: which step are you stuck on right now - wedge/dash, rotations, or the definition of enantiomers?
