Question

Can you check My work and tell me if these are right regarding if they are R rotating or S rotations, please? Thank you. 

**Title: Understanding Stereochemistry: R & S Configurations**

This educational page aims to explain the R (Rectus) and S (Sinister) configurations in stereochemistry with examples.

---

**1. Example a):**

- Structure: Amine group (\(NH_2\))
- Configuration: R

**2. Example b):**

- Structure: Benzene derivative with Bromine (Br)
- Configuration: S

**3. Example c):**

- Structure: Chlorine (Cl) attached, numbered 1 to 4
- Configuration: S

**4. Example d):**

- Structure: Cyclohexane chair conformation with Chlorine (Cl)
- Configuration: S

**5. Example e):**

- Structure: Furan derivative
- Configuration: R

**6. Example f):**

- Structure: Cyclohexanol with adjacent substituents
- Configuration: S

**7. Example g):**

- Structure: Chemical with acetal group
- Configuration: S

**8. Example h):**

- Structure: Nitrile group (\(CN\)) attached
- Configuration: S

**9. Example i):**

- Structure: A complex bicyclic compound
- Configuration: R

**10. Example j):**

- Structure: A ketone within a ring structure
- Configuration: R

**Additional Notes:**

- *Clockwise is R, Counter-clockwise is S*: It has been annotated that when the priorities decrease in a clockwise manner, the configuration is R. Conversely, a counter-clockwise decrease indicates an S configuration.

Through these examples, students can comprehend how to denote the R and S configurations by considering the spatial arrangement of atoms or groups around a chiral center, following Cahn-Ingold-Prelog priority rules.
