Question
**2.2A2: Stereochemistry Analysis**

**Concepts Covered:**

- Stereocenters 
- Chirality 
- Symmetry 
- Labeling Enantiomers/Diastereomers
- Absolute Configurations (R/S)
- E/Z Isomerism

**Instructions:**

Apply the CTP (Cahn-Ingold-Prelog) Rules to accurately label the provided chemical structures. Identify each as either an enantiomer or diastereomer, and determine the R/S absolute configurations for each stereocenter. If applicable, also assign E/Z configurations.

**Structure Illustrations:**

1. **First Structure:**
   - Configuration: (R, R, R)
   - Diagram: A bicyclic structure with methyl (CH₃) substituents.

2. **Second Structure:**
   - Configuration: (S, S, S)
   - Diagram: An aromatic ring with methoxy (OCH₃) and methyl (CH₃) substituents. 

**Tasks:**

- Draw a wedge and dash representation for the isomers.
- Label all identifiable groups.
- Clarify any E/Z isomerism involved, ensuring to clearly show your work.

By examining the structural arrangement and applying these rules, you will enhance your understanding of the importance of stereochemistry in organic compounds.
