Question
**Determine the major product (include stereochemistry)**

- **Reaction:** 
  - Starting Material: Naphthalene structure
  - Reagents: Potassium permanganate (\[\text{KMnO}_4\]) and sodium hydroxide (\[\text{NaOH}\]), under cold conditions.
  - The structural formula of the product is shown, representing an open chain diol.

**Explanation:**

This reaction illustrates the oxidative cleavage of a naphthalene compound using \[\text{KMnO}_4\] in basic conditions. The product is a diol, specifically one with open chain structure suggesting oxidative cleavage across the two benzene rings of the naphthalene. The stereochemistry of the diol should be considered, as \[\text{KMnO}_4\]-mediated oxidation can lead to syn diols. 

**Chemical Concepts:**

- **Oxidative Cleavage:** Involves breaking carbon-carbon bonds and transforming them into carbon-oxygen bonds.
- **Stereochemistry:** Refers to the spatial arrangement of atoms in molecules and their impact on chemical properties.

This transformation is typical in organic chemistry for converting aromatic systems into more oxidized products, often used in synthetic pathways.
