Why Enantiomeric Excess Calculations Confuse Everyone

Optical activity is one of the most tested AND MISUNDERSTOOD topics in organic chemistry. This isn't JUST calculations, but the background info you need to make sense of it all. You’ll learn how to interpret polarimeter data, understand observed rotation and racemic mixtures, and see what each number in the calculation actually means. Instead of memorizing formulas, you’ll build real understanding.
