please label E/Z configuration and priority on products!!

**Question 5:**

For the following molecule, how many isomeric forms of alkenes could be made by reacting this with sodium isopropoxide (alkoxide of isopropyl alcohol) in isopropyl alcohol solution at 75°C?

Show the process for the reaction and label and name all products expected to be made. Which one product is likely the major product? Remember E/Z as you name them.

*Diagram Description:*

The diagram shows a chlorinated organic molecule. The structure consists of a carbon chain with a chlorine (Cl) substituent. The details of the molecular structure are crucial for determining the possible alkenes formed in the reaction. The mechanism involves dehydrohalogenation, a base-induced elimination reaction (E2), to form alkenes from haloalkanes.

---

**Analysis & Explanation:**

Reacting the given haloalkane with a strong base such as sodium isopropoxide results in the elimination of the halide ion (Cl⁻) and a hydrogen ion (H⁺) from adjacent carbon atoms, leading to the formation of an alkene. The reaction conditions at 75°C favor the formation of the most stable alkene, often leading to isomeric variations based on different possible positions for the double bond (E/Z isomerism).

1. **Identify β-Hydrogens:**
   Recognize all hydrogen atoms adjacent to the carbon with the halide group.

2. **Elimination Pathways:**
   - Draw possible alkene structures.
   - Consider the steric and electronic factors that stabilize each potential alkene.
   
3. **Naming E/Z Isomers:**
   Apply the Cahn-Ingold-Prelog (CIP) priority rules to name E (entgegen) and Z (zusammen) isomers.

4. **Identify Major Product:**
   The most substituted (stable) alkene, following Zaitsev’s rule, is typically favored as the major product.

This assessment helps predict the outcome of elimination reactions to synthesize desired alkenic products in organic chemistry.
