**Instructions for Drawing Structural Formulas of Branched Constitutional Isomers**

**Objective:**
Draw the structural formula(s) for the branched constitutional isomer(s) with the molecular formula \(C_7H_{16}\) that do not have a methyl group.

**Steps:**

1. **Drawing a Structure:**
   - Use the sketcher tool to draw one structure at a time.
   - Ensure each sketched structure adheres to the molecular formula \(C_7H_{16}\).

2. **Adding Additional Structures:**
   - To add more structures, use the drop-down menu located in the bottom right corner of the sketcher interface.
   - Each new structure should be created on a new sketcher.

3. **Separating Structures:**
   - Separate each structure with a plus sign (+). This can be done using the options available in the drop-down menu.

**Sketcher Tools Guide:**
- The sketcher tool includes various options for creating molecular structures, which include:
  - **Element Selection**: Choose different elements for constructing your molecule.
  - **Bond Types**: Add single, double, triple, or stereochemical bonds.
  - **Shapes**: Use preset shapes like hexagons and other polygons for ring structures.
  - **Undo/Redo**: Correct mistakes or revert changes.
  - **Copy/Paste**: Duplicate structures or parts of structures as needed.
  - **Advanced Editing**: Includes options for modifying bond angles, lengths, and other molecular geometries.

- The central drawing area, powered by ChemDoodle, allows you to visually construct and edit your molecular model.

**Finalizing Structures:**
- Review each structure ensuring it conforms to the molecular formula \(C_7H_{16}\) without incorporating any methyl groups.
- The interface allows you to preview, edit, and remove structures as necessary.

By following these steps, you can effectively use the drawing tools provided to create accurate structural formulas for the given molecular formula and conditions.

**Title: Understanding Structural Formulas in Compounds**

**Instructions:**
Compare the two structural formulas in each set. Do they represent the same compound, represent constitutional isomers, or represent two compounds which are neither identical nor constitutional isomers?

**Set Descriptions and Possible Answers:**

1. **Set a:**
   - Structure 1: A compound with an OH group attached to a three-carbon chain (a primary alcohol).
   - Structure 2: A compound with an OH group attached to a different position of the carbon chain, making it an isomer of the first compound.
   - **Drop-down Answer Options:** 
     - Identical Compounds
     - Constitutional Isomers (Selected)
     - Neither

2. **Set b:**
   - Structure 1: A compound with an NH group attached to the carbon chain, with a double bond indicated.
   - Structure 2: A compound with an NH2 group attached to a different position of the carbon chain, indicating another isomer.
   - **Drop-down Answer Options:** 
     - Identical Compounds
     - Constitutional Isomers
     - Neither

3. **Set c:**
   - Structure 1: A compound with an OH group attached to a cyclohexane ring.
   - Structure 2: A compound drastically different from the first, likely neither an isomer nor identical compound.
   - **Drop-down Answer Options:** 
     - Identical Compounds
     - Constitutional Isomers
     - Neither
