Explain :
Ethyl isobutyrate does not undergo Claisen condensation in the presence of `NaOEt`.

Explanation

To understand why ethyl isobutyrate does not undergo Claisen condensation in the presence of sodium ethoxide (NaOEt), we can break down the explanation into several steps:

### Step 1: Understanding the Structure of Ethyl Isobutyrate
Ethyl isobutyrate has the following structure:
- It consists of an isobutyrate group (which is a branched carboxylic acid) attached to an ethyl group.
- The molecular formula can be represented as CH3C(CH3)COOEt.

### Step 2: The Requirement for Claisen Condensation
