**Title: Identifying the Expected Major Product of a Reaction Sequence**

**Introduction:**
In this exercise, we will determine the expected major product resulting from a specific organic reaction sequence. The reaction sequence involves an initial compound reacting with ozone (O₃) followed by water (H₂O). 

**Reaction Sequence:**
The initial compound is a cyclohexene derivative with the following reaction conditions:
1. O₃ (ozone)
2. H₂O (water)

**Possible Products:**
The reaction leads to five potential products, labeled I, II, III, IV, and V. Identify which one is the major product expected from the reaction sequence.

**Compounds:**
- **Compound I:** A 7-membered ring with an epoxide at the 2nd position.
- **Compound II:** A 7-membered ring with carboxylic acid groups at the 2nd and 5th positions.
- **Compound III:** A 7-membered ring with aldehyde groups at the 2nd and 5th positions.
- **Compound IV:** A 7-membered ring with ketone groups at the 2nd and 5th positions.
- **Compound V:** A 7-membered ring with a carboxylic acid at the 2nd position and an aldehyde group at the 5th position.

**Potential Answers:**

A. I
B. II
C. III
D. IV
E. V

To determine the expected major product, we will analyze the reaction sequence step-by-step:

1. **Ozonolysis (O₃)**: This step involves the cleavage of the double bond in cycloalkene, forming an ozonide.
2. **Reduction or Hydrolysis (H₂O)**: The ozonide subsequently breaks down to produce carbonyl-containing compounds.

**Conclusion:**
Based on the ozonolysis followed by hydrolysis, the most stable products typically involve ketones or carboxylic acids. In essence, the major expected product of this reaction sequence reiterates the addition of oxygen to the former double-bond locations, leading to the creation of aldehydes or carboxylic acids.

**Answer:**
Upon analysis, the expected major product of the reaction sequence is **Compound III** (Choice C), representing the formation of appropriate aldehyde groups resulting from ozonolysis followed by reaction with water.
