Explanation

To complete the reaction of benzaldehyde with ethyl acetate in the presence of sodium ethoxide and ethanol, we can follow these steps:

### Step 1: Identify the Reactants
- The reactants are benzaldehyde (C₆H₅CHO) and ethyl acetate (CH₃COOC₂H₅).

### Step 2: Role of Sodium Ethoxide
- Sodium ethoxide (NaOC₂H₅) acts as a strong base. It will deprotonate the α-hydrogen of the ethyl acetate, leading to the formation of a carbonyl anion.
