### Polar C₂H₂Br₂ Structures (Two Structures)

#### Instructions:
To draw the two polar structures of C₂H₂Br₂, follow the guidelines below with the provided drawing tools.

1. **Select Tool**: Use this to select and manipulate parts of your drawing.
2. **Drawing Tool**: Use the single, double, or triple bond tools to create the structure.
   - Single bond: Represented by a single line.
   - Double bond: Represented by a double line.
   - Triple bond: Represented by a triple line.
3. **Elements**: Click on the atoms (C, H, Br) to place them in the structure.

#### Explanation:
1. **Draw the Carbon Backbone**:
   - Start with two carbon (C) atoms connected by a single or double bond.
   
2. **Assign Hydrogen (H) and Bromine (Br) Atoms**:
   - Attach hydrogen (H) and bromine (Br) atoms to the carbon atoms ensuring the structure results in a net dipole moment.

3. **Verify Polarity**:
   - Ensure the structures reflect the physical property of polarity (i.e., one end of the molecule is slightly negative, while the other end is slightly positive).

#### Example Structures:
Below are two example structures that showcase possible configurations for C₂H₂Br₂, ensuring polarity.

---

**Graphical User Interface Description**:
- The interface includes a section for selecting drawing tools and elements (C, H, Br) to construct molecular structures.
- Undo/Redo options are provided for corrections.
- Additional templates might be available for more complex structures.

#### Additional Help:
For further assistance or examples, you can refer to the publisher's guide or explore more templates available under the "Templates" tab.

#### Source Citation:
The question information is derived from McQuarrie, Rock, And Gallogly in the 4th edition of "General Chemistry," published by University Science Books.

### Exploring Dibromoethene Isomers

Dibromoethene, with the molecular formula \( \text{C}_2 \text{H}_2 \text{Br}_2 \), can exist in three different isomeric forms. Among these isomers, one has no net dipole moment (nonpolar), while the other two are polar. This exercise helps visualize these structures using Lewis diagrams.

#### Task Description

Draw the Lewis structures for each isomer of dibromoethene. Make sure to include Hydrogen (H) atoms in your diagrams.

1. **Nonpolar \( \text{C}_2 \text{H}_2 \text{Br}_2 \) Structure (one structure)**

Provide a detailed step-by-step construction of the nonpolar isomer's Lewis structure:

- **Step 1:** Use bond line notation to represent the atoms and their connections.
- **Step 2:** Use the 'C', 'H', and 'Br' buttons to place the appropriate atoms in the structure.
- **Step 3:** Ensure all valence electrons are correctly placed to satisfy the octet rule for carbon and appropriate valence for hydrogen and bromine.

This will visually depict the nonpolar form of the molecule and provide a clear understanding of how double bonds and substituents affect polarity.

---

#### Example Setup

Imagine we're using a software tool to draw these structures:

- **Select Tool:** Allows selection of the bond type (single, double, triple).
- **Draw Tool:** Engages the drawing process for the molecular structure.
- **Templates and More:** Additional tools for creating and modifying chemical structures.
- **Erase Tool:** To correct any mistakes, an eraser is available.
