Explain with the help of chemical reaction :
Two molecules of benzaldehyde are treated with conc . NaOH

Explanation

To explain the reaction of two molecules of benzaldehyde with concentrated NaOH, we will discuss the mechanism of the Cannizzaro reaction, which occurs in the absence of alpha-hydrogens. Here’s a step-by-step breakdown of the reaction:

### Step 1: Identify the Reactants
We start with two molecules of benzaldehyde (C₆H₅CHO). The structure of benzaldehyde is as follows:
