Isomers Part II

Organic Chemistry 1
Summary
The lesson delves into the intricate world of optical isomers, their subtypes, and the principles governing their behavior and characteristics, focusing on chirality, enantiomers, diastereomers, and meso compounds.
- Optical isomers are a subtype of configurational isomers differentiated by how polarized light is rotated when passing through them, attributed to their molecular chirality.
- Enantiomers are mirror images with opposite chirality at every chiral center, affecting how they interact with polarized light and chiral catalysts like enzymes.
- Diastereomers have different stereochemistry but are not mirror images of each other, leading to varied physical properties and chemical reactivities.
- Meso compounds, despite having chiral centers, do not rotate plane-polarized light due to an internal mirror plane that cancels out optical activity.
- The number of potential optical isomers can be calculated using the Van't Hoff Rule, with adjustments for meso compounds, which are considered as a single isomer despite being a pair.
