Question

**Determine the Configuration of Chiral Centers**

In the provided molecular structure, you are tasked with specifying the configurations (R or S) of chiral centers labeled as **a** and **b**.

### 2D Structural Diagram:

- The diagram shows a cyclic compound featuring two chiral centers.
- **Chiral Center a:** Connected to an ethyl (CH<sub>2</sub>CH<sub>3</sub>), hydroxyl (OH), and other substituents within the ring.
- **Chiral Center b:** Connected to a methyl group (CH<sub>3</sub>) and other constituents.

### 3D Molecular Model:

The interactive 3D model beside the structural diagram visualizes the same compound using a ball-and-stick representation. Each atom is represented as a sphere, and bonds as sticks, with colors indicating different elements:
- **Carbon (gray)**
- **Oxygen (red)**
- **Hydrogen (white)**

Use the drop-down menus to select the configuration (R or S) based on the three-dimensional orientations of the substituents.

Selections:
- **Carbon a:** [Dropdown menu for R/S configuration]
- **Carbon b:** [Dropdown menu for R/S configuration]

### Instructions:

1. Observe the priorities of the substituents attached to each chiral center using the Cahn–Ingold–Prelog priority rules.
2. Determine the 3D arrangement and direction of the substituents to assign R (rectus) or S (sinister) configuration.
3. Use the drop-down menus to select the correct configurations for Carbons a and b based on your analysis.

The image depicts a 3D molecular model of camphor. In this model, different colored spheres represent specific atoms within the compound:

- **Gray spheres**: Carbon atoms
- **White spheres**: Hydrogen atoms
- **Red spheres**: Oxygen atoms

The structure is characteristic of camphor, displaying a bicyclic framework. The molecule includes two fused rings made primarily of carbon and hydrogen, with an oxygen atom attached to one of the carbons in the ring system. This arrangement is typical for camphor, known for its aromatic odor and various applications ranging from medicinal uses to being a component in incense.
