Acetophenone hydrazone when heated with KOH in ehtylene glycol at 453 K gives_____. This is known as________.

Explanation

To solve the question, we will go through the steps involved in the reaction of acetophenone hydrazone when heated with KOH in ethylene glycol.

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactant in this case is acetophenone hydrazone. Acetophenone has the structure \( \text{C}_6\text{H}_5\text{C(O)CH}_3 \) and when it reacts with hydrazine, it forms acetophenone hydrazone, which has the structure \( \text{C}_6\text{H}_5\text{C(NH}_2\text{)CH}_3 \).

2. **Understand the Reaction Conditions**:
