Question
**Title: Understanding Reaction Mechanisms: Stereochemistry with Organic Reactions**

**Objective:**  
Learn to draw the major product of a given organic reaction and illustrate the stereochemistry using wedge and dash bonds. 

---

**Problem Statement:**  
*Draw the major product from this reaction. Use wedge and dash bonds to indicate relative stereochemistry where appropriate. Ignore inorganic byproducts.*

**Chemical Reaction Details:**  
- **Starting Compound:** The starting compound is an alkene with a tetrasubstituted double bond. The structural formula shows a two-carbon chain (ethyl group) branching from a longer, more complex carbon framework.
- **Reagents Used:** 
  - **tBuOK (Potassium tert-butoxide):** A strong base often used in elimination reactions.
  - **CHCl₃ (Chloroform):** Can act as a solvent or a reactant in the formation of carbenes.

**Expected Product:**  
- **Reaction Type:** This reaction is likely to involve a carbene intermediate due to the presence of chloroform in basic conditions.
- **Expected Major Product Features:** A cyclopropanation might occur involving the intermediate carbene, adding to the double bond in the starting compound. Use of stereochemical markings (wedge and dash) is necessary to show the spatial arrangement of atoms. 

---

**Instructions for Drawing the Major Product:**

1. **Visualize the Reactants and Reagents:**
   - Consider the role of tBuOK as a base and the potential formation of carbenes from CHCl₃.

2. **Predict the Reaction:**
   - Anticipate a cyclopropanation at the alkene site due to carbene interaction.

3. **Incorporate Stereochemistry:**
   - Use wedge and dash bonds to indicate any new chiral centers or relative stereochemistry in the 3-membered ring formed.

*Note: Ensure clarity in your structural drawings to effectively communicate the stereochemical outcomes.*

---

**Conclusion:**  
By understanding the nature of the reactants and reaction conditions, and incorporating proper stereochemistry notations, you can predict and draw the major product of this organic reaction accurately.
