### Chemical Reaction: Benzil to Hexan-2,5-dione

#### Reactants:
- **Benzil:** The structure on the left shows a benzene ring with two ketone groups on adjacent carbon atoms.
  
#### Products:
- **Hexan-2,5-dione:** The structure on the right is a linear six-carbon chain with ketone groups on the second and fifth carbon atoms.

#### Reaction Conditions:
- **Reagents:** Sodium hydroxide (NaOH) and ethanol (EtOH)
- **Process:** Reflux

#### Process Explanation:

This transformation shows the conversion of benzil into hexan-2,5-dione under basic conditions using sodium hydroxide in an ethanol solvent. The process involves reflux, a technique where the reaction mixture is heated to boiling and the vapor is condensed back to liquid, allowing continuous heating without loss of solvent.
