This image contains two separate chemical reaction schemes, each depicting reactions involving organic compounds with specific reagents and conditions.

#### Reaction Scheme 1:
- **Reactant**: 
  - Starting material is a ketone with the structure \( \text{CH}_3\text{C(O)CH}_2\text{CH}_3 \).
- **Reagents and Conditions**:
  - Sodium ethoxide (NaOEt) in ethanol (EtOH) is used as a base.
- **Description**: 
  - The reaction involves a carbonyl compound, where the base likely facilitates an enolate formation or a similar transformation.

#### Reaction Scheme 2:
- **Reactants**: 
  - Starting material is an aromatic diketone, specifically an ortho-diketone (1,2-diketone) with the structure benzil, \((\text{C=O})\text{C}_6\text{H}_5(\text{C=O})\).
  - Another compound is a dialdehyde with the structure \(\text{OHC-CH}_2\text{-CH}_2\text{-CHO}\).
- **Reagents and Conditions**:
  - Sodium hydroxide (NaOH) in ethanol (EtOH) under reflux conditions.
- **Description**:
  - This reaction likely involves a base-catalyzed condensation or addition reaction. Reflux is used to maintain the reaction at a temperature that allows for completion without loss of solvent.

This image provides examples of base-catalyzed reactions in organic chemistry, highlighting the versatility of carbonyl chemistry in constructing complex molecular architectures.
