Question

**Title: Reaction of 1-Chloro-1-methylcyclopentane with Potassium tert-Butoxide**

**Introduction:**
In this reaction, 1-chloro-1-methylcyclopentane undergoes dehydrohalogenation when reacted with potassium tert-butoxide in warm tert-butanol, leading to the formation of alkene products.

**Reaction Details:**
- **Reagents**:
- 1-Chloro-1-methylcyclopentane
- Potassium tert-butoxide
- Warm tert-butanol (solvent)

**Mechanism Overview:**
The reaction is a classic example of an E2 elimination mechanism, where the strong base (potassium tert-butoxide) abstracts a proton, and the leaving group (chlorine) departs simultaneously, forming a double bond.

**Expected Product Mixture:**
- The reaction yields a mixture of alkenes.
- Among the products, the major one is typically the more substituted alkene due to Zaitsev's rule.

**Conclusion:**
This reaction demonstrates the use of a strong base in promoting E2 eliminations, yielding alkenes, and highlights the significance of regioselectivity (Zaitsev's rule) in determining the major product.
