### Explanation

The task involves determining the stereochemistry of chiral centers within organic molecules, labeling them as either R (rectus) or S (sinister) based on the Cahn-Ingold-Prelog priority rules. Each molecule depicted includes one or more chiral centers that need to be analyzed.

- **Chiral centers** are typically marked by a central carbon atom bounded by four distinct groups.
- **Priority** is assigned based on the atomic number; highest priority is given to the atom with the highest atomic number directly bonded to the chiral center.
- **R/S Configuration** is determined by arranging the molecule so that the lowest priority group is oriented away from the observer, viewing the sequence in decreasing priority.

This exercise assists in understanding stereochemistry, an important aspect of molecular geometry affecting chemical behavior and biological interactions.
