### Organic Chemistry Reactions

Below are the reaction schemes and reagents used for various organic transformations starting with a six-membered ring structure as the base compound.

1. **Initial Reaction Scheme**

    - **Reactant:** Six-membered ring with one double bond (cyclohexene).
    - **Reagents:**
        1. **Step 1:** O<sub>3</sub> at -78°C (Ozonolysis).
        2. **Step 2:** (CH<sub>3</sub>)<sub>2</sub>S (Dimethyl sulfide).
    - **Product:** Results in the cleavage of the double bond.

2. **Oxidation Reaction Scheme**

    - **Reactant:** Six-membered ring with double bond.
    - **Reagents:**
        - KMnO<sub>4</sub> in the presence of H<sub>2</sub>O and heat.
    - **Product:** This oxidizes the double bond.

3. **Bromination Reaction Scheme**

    - **Reactant:** Six-membered ring with double bond.
    - **Reagent:** Br<sub>2</sub> in a CCl<sub>4</sub> solvent (Bromination).
    - **Product:** Forms a brominated compound.

4. **Hydroboration-Oxidation Reaction Scheme**

    - **Reactant:** Six-membered ring with double bond.
    - **Reagents:**
        1. Hg(OAc)<sub>2</sub> in H<sub>2</sub>O.
        2. NaBH<sub>4</sub> (Sodium borohydride).
    - **Product:** Forms an alcohol through hydroboration-oxidation.

### Diagram Explanation

The diagram presents a schematic progression for different chemical reactions of a six-membered carbon ring (cyclohexene). Each reaction starts from the same base compound but proceeds with different reagents resulting in various products:

1. **Ozonolysis**: Uses ozone and dimethyl sulfide to cleave the double bond.
2. **Oxidation**: Potassium permanganate with water and heat to oxidize the ring.
3. **Bromination**: Bromine in carbon tetrachloride to add bromine across the double bond.
4. **Hydroboration-Oxidation**:
