What is the action of 2, 4-dinitrophenyl hydrazine on acetaldehyde ?

Explanation

To understand the action of 2,4-dinitrophenylhydrazine on acetaldehyde, we can break down the process into several steps:

### Step 1: Identify the Reactants
- **Acetaldehyde (C₂H₄O)**: This is the aldehyde that will react with 2,4-dinitrophenylhydrazine.
- **2,4-Dinitrophenylhydrazine (C₆H₃(N₂H₃)(NO₂)₂)**: This is the reagent that will react with the carbonyl group of acetaldehyde.

### Step 2: Mechanism of Reaction
- The reaction involves the nucleophilic addition of 2,4-dinitrophenylhydrazine to the carbonyl carbon of acetaldehyde.
