Question

A compound with the formula C8H12 absorbs two equivalents of H2 on Catalina reduction over a palladium catalyst to give compound A. Ozonalysis oxidative cleavage of the unknown compounds gives two compounds B and C. 

### Degrees of Unsaturation in Organic Compounds

**Problem Statement:**

Consider the given chemical reactions and structures to determine the following for the initial compound:

(a) How many degrees of unsaturation does the compound have?

(b) How many double bonds, and how many rings does it have?

**Diagram Explanation:**

- The initial compound is represented as a hexagon at the top, labeled as **Compound A**.
- Using the reagent Pd/C with H₂, Compound A is converted into another structure, depicted as a six-membered cyclohexane, implying the complete hydrogenation of Compound A. 

- Additionally, Compound A undergoes ozonolysis:
  1. With O₃ (ozone) in the first step.
  2. Followed by Zn, H₃O⁺ in the second step, resulting in the formation of **Compounds B & C**.

**Structure Analysis:**

- **Compounds B & C** are shown as:
  - Compound B: A structure containing two carbonyl groups (O=C).
  - Compound C: Similar to B, but longer, with an extra carbon and another carbonyl group.

**Definitions:**

- **Degrees of Unsaturation:** Each degree of unsaturation corresponds to a ring or a double bond present in the compound.

### Conclusion:

Analyze the conversion and breakdown of Compound A to determine its unsaturated components, aiding in identifying the double bonds and rings present initially. Use the data from the given structures and processes to fill in the blanks provided in your educational textbook.
