The Cannizzaro's reaction is not given by `:`

Options

A. Trimethyl acetaldehyde
B. Acetaldehyde
C. Benzaldehyde
D. Formaldehyde

Explanation

To determine which compound does not undergo the Cannizzaro reaction, we need to identify the presence or absence of alpha hydrogen in each compound. The Cannizzaro reaction occurs with aldehydes that lack alpha hydrogen.

### Step-by-Step Solution:

1. **Understanding Cannizzaro Reaction**:
- The Cannizzaro reaction involves the disproportionation of aldehydes that do not have alpha hydrogen when treated with a strong base (like NaOH).
- Aldehydes without alpha hydrogen will be oxidized to carboxylic acids and reduced to alcohols.
