**Identify the equilibrium below that shows the two chair conformations of the following compound:**

The structure of the compound shown has a bromine (Br) substituent attached to a cyclohexane ring.

Below this instruction, there are three options presented as diagrams of chair conformations in equilibrium. Here is a detailed explanation of each option:

1. **First Diagram:**
   - The diagram shows two chair conformations of cyclohexane, with a double-headed arrow indicating equilibrium between them.
   - In the left chair conformation, the bromine substituent (Br) is positioned in the axial position.
   - In the right chair conformation, the bromine substituent (Br) is positioned in the equatorial position.

2. **Second Diagram:**
   - This diagram also shows two chair conformations of cyclohexane in equilibrium.
   - In the left chair conformation, the bromine substituent (Br) is positioned in the equatorial position.
   - In the right chair conformation, the bromine substituent (Br) is positioned in the axial position.

3. **Third Diagram:**
   - The diagram again shows two chair conformations of cyclohexane in equilibrium.
   - In both the left and right chair conformations, the bromine substituent (Br) appears to be in the axial position.

The task is to identify which of these diagrams correctly illustrates the equilibrium between the two chair conformations of the given compound.

**Question 18 of 25**

Identify the equilibrium below that shows the two chair conformations of the following compound:

[Diagram of a hexagon with one carbon having a substituent]

- Option 1: 
  ![Two chair conformations with arrows indicating equilibrium]
- Option 2: 
  ![Two chair conformations with arrows indicating equilibrium]
- Option 3: 
  ![Two chair conformations with arrows indicating equilibrium]

**Instruction for selecting the correct option:**
There are three sets of diagrams provided. Each set includes two cyclic structures with arrows between them, representing potential equilibria of different conformations. Review each set to determine which one correctly shows the two chair conformations of the compound displayed above.

Please select the correct option that accurately represents the two chair conformations of the specified compound.

**Note:** Chair conformations are the most stable forms of cyclohexane due to their minimized steric strain and torsional strain. The 'chair flip' is an equilibrium process that interconverts the two chair forms.
