Question

What is the product of the following Reaction?

**Image Description and Reaction Mechanism Explanation:**

The image shows a chemical reaction where a cyclic alkene is reacted with meta-chloroperoxybenzoic acid (CH₃CO₃H) followed by hydronium ion (H₃O⁺) in two separate steps. This is generally indicative of an epoxidation followed by acidic opening of the epoxide.

**Reaction Steps:**

1. **Reagents:**
   - **1) CH₃CO₃H:** This represents a peroxyacid (specifically mCPBA, though not shown as meta-chloro specifically here), used commonly for epoxidation of alkenes.
   - **2) H₃O⁺:** This indicates acidic conditions, often used to open epoxides.

2. **Products:**
   - Structures labeled A, B, C, D, E are potential diol products formed after the reaction. These are each pentane diols, with the hydroxyl groups (-OH) located potentially at vicinal (neighboring) carbon atoms, a result of epoxide opening.
   - The stereochemistry of the hydroxyl groups at these positions varies, as indicated by the wedge (bold) and dashed (thin) bonds:
     - **A:** Both hydroxyls are trans to each other.
     - **B:** Both hydroxyl groups are cis, with one carbon having substituents above the plane.
     - **C:** Both hydroxyls are cis, with the opposite configuration compared to B.
     - **D:** The product has trans hydroxyls with opposite configuration as A.
     - **E:** Another cis configuration similar to C but flipped.

**Explanation of Concepts:**

- **Epoxidation Reaction:** Alkenes react with peroxy acids to form epoxides. This reaction usually occurs in a stereospecific manner, retaining the stereochemistry of the original alkene.

- **Acid-Catalyzed Epoxide Opening:** The treatment with H₃O⁺ opens the epoxide to form a diol. The reaction can lead to various stereochemical outcomes, depending on the reaction conditions, the nature of the epoxide, and the mechanism followed (SN1-like or SN2-like).

- **Stereochemistry Notation:**
  - **Wedged Bonds:** Represent bonds coming out of the plane (towards the viewer).
  - **Dashed Bonds:** Represent
