X-ray Reveals the Truth. R/S Makes It Speak.
Why stereochemistry is not just about seeing molecules—but learning how to describe them In modern chemistry, we have powerful tools like X-ray crystallography that can reveal the exact three-dimensional structure of a molecule with remarkable precision. So it raises a compelling question: If we already know what a molecule truly looks like in 3D… why do we still assign R/S configuration on a flat 2D drawing? Is it redundancy—or something deeper? 🔬 Discovery vs Description …
