### Reaction Pathway for Alkene Reactions

#### Diagram Explanation:

This diagram represents an alkene subjected to different oxidative conditions leading to various organic products. 

1. **Central Alkene Structure**
   - The central structure is an alkene: 2-methyl-2-butene.

2. **First Reaction Pathway (Top Left)**
   - **Reagent:** mCPBA (meta-Chloroperoxybenzoic acid)
   - **Reaction Outcome:** Leads to the formation of an epoxide.
   - **Drawing Placeholder:** "Select to Draw" for the specific epoxide product is indicated.

3. **Second Reaction Pathway (Top Right)**
   - **Reagents:** 
     1. Ozone (O₃)
     2. Hydrogen Peroxide (H₂O₂)
   - **Reaction Outcome:** This is a two-step oxidative cleavage of the alkene resulting in the formation of carboxylic acids.
   - **Drawing Placeholder:** "Select to Draw" for the specific carboxylic acid products is indicated.

4. **Third Reaction Pathway (Bottom Left)**
   - **Reagents:** 
     1. Ozone (O₃)
     2. Dimethyl Sulfide ((CH₃)₂S)
   - **Reaction Outcome:** This two-step process results in the formation of aldehydes instead of carboxylic acids.
   - **Drawing Placeholder:** "Select to Draw" for the specific aldehyde products is indicated.

5. **Fourth Reaction Pathway (Bottom Right)**
   - **Reagents:** 
     1. Ozone (O₃)
     2. Zinc in acidic conditions (Zn/H₃O⁺)
   - **Reaction Outcome:** This two-step process leads to the formation of ketones and aldehydes.
   - **Drawing Placeholder:** "Select to Draw" for the specific ketone and aldehyde products is indicated.

#### Visual Summary:
- The chart diagrammatically showcases the versatility of oxidative reactions on an alkene, leading to various significant organic products like epoxides, carboxylic acids, aldehydes, and ketones.

This visual aid is very useful for understanding organic chemistry reaction mechanisms and predicting the outcome of reactions based on the chosen reagents and conditions.

# Predicting the Major Product of Alkene Reactions

## Objective:
A common alkene starting material is shown below. Predict the major product for each reaction. Ignore any inorganic byproducts.

## Reactions:

### Reaction 1:
1. Reactant: Alkene
   - Reagent: mCPBA (m-Chloroperoxybenzoic acid)
   - Product: (to be drawn by the user)

### Reaction 2:
1. Reactant: Alkene
   - Reagents: 
      1. O₃ (Ozone)
      2. H₂O₂ (Hydrogen Peroxide)
   - Product: (to be drawn by the user)

### Reaction 3:
1. Reactant: Alkene
   - Reagents: 
      1. O₃ (Ozone)
      2. (CH₃)₂S (Dimethyl Sulfide)
   - Product: (to be drawn by the user)

### Reaction 4:
1. Reactant: Alkene
   - Reagents: 
      1. O₃ (Ozone)
      2. Zn / H₃O⁺ (Zinc in acidic conditions)
   - Product: (to be drawn by the user)

### Starting Material:
The starting material is a common alkene represented by the molecular structure in the center of the diagram. It consists of a carbon chain with a double bond.

### Instructions:
1. Use the given reagents and conditions for each reaction.
2. Draw the major organic product for each reaction, ignoring any inorganic byproducts.
3. Utilize the reaction conditions to guide your prediction of the products.

By understanding and applying the principles of these reactions, students can predict the structures of the resultant products accurately. Each reagent interacts differently with the alkene, leading to varied products based on the pathway of the chemical reaction.

Educational Notes:
- **mCPBA** is often used for epoxidation of alkenes.
- **Ozonolysis** with **O₃ followed by H₂O₂** generally leads to carboxylic acids.
- **Ozonolysis** with **O₃ followed by (CH₃)₂S or Zn/H₃O⁺** typically results in aldehydes or ketones.

_Further Reading:_ Students are encouraged to consult their organic chemistry textbooks or peer-reviewed journals for detailed mechanisms and examples
