Question

I need help with these problems. I am completely lost when it comes to organic chem. 

**Instructions**

2. Consider the diagram below.

[Diagram with three rectangular boxes connected by arrows to a central compound, with one additional arrow leading to a product]

**Diagram Explanation:**

- **Center Compound:** The central structure is cyclohexene.
- **Reactions:**
  - **HBr Reaction:** An arrow from cyclohexene points to a box labeled "HBr."
  - **BH₃, THF / NaOH, H₂O₂ Reaction:** An arrow from cyclohexene points to a box with the reaction conditions: 
    1. BH₃, THF
    2. NaOH, H₂O₂
  - **H₃O⁺ Reaction:** An arrow from cyclohexene points to a box labeled "H₃O⁺."
  - **H₂, Ni Reaction:** An arrow from cyclohexene points downward to an empty box.
  - **Product Reaction:** The final arrow points rightward to a compound with a chlorine branching from a six-membered ring.

**Tasks**

a. Fill in the missing products for each reaction.

b. Pick **two** of the five reactions shown above and draw the mechanism, showing the step-by-step process with arrows to get from the starting material to the products.

3. Consider the following reaction:

The diagram illustrates a multi-step chemical reaction with four steps. Below is the explanation for each step and the accompanying tasks:

**Step 1:**
- The reactant box is blank. This space requires identification of the starting material. It reacts to form a new compound.

**Step 2:**
- A new compound is formed, displayed in a box. The next reactant needs identification.

**Step 3:**
- Another unidentified reactant combines with the Step 2 product. The reaction forms a complex with a Br anion.

**Step 4:**
- Involves the use of Br₂ and DCM (dichloromethane) in the reaction. This step requires filling in the final product.

**Tasks:**

a. **Fill in the missing starting materials, products, and reagents:**
   - Complete the reaction by identifying the necessary missing components in each step.

b. **Draw the mechanism for Step 1 using curved arrows:**
   - Illustrate the electron flow and provide a detailed mechanism for the first step.

c. **Draw the mechanism for Step 2 using curved arrows:**
   - Provide a detailed mechanism for the second step, showing all electron movements.

d. **Draw the mechanism for Step 4 using curved arrows:**
   - Present the electron flow and detailed mechanism for the final step.

This problem invites exploration of reaction mechanisms, including identifying reagents, products, and illustrating electron movements with curved arrows.
