How will you prepare methanol from formaldehyde without using a reducing agent.

Explanation

To prepare methanol from formaldehyde without using a reducing agent, we can utilize the Cannizzaro reaction. Here’s a step-by-step breakdown of the process:

### Step-by-Step Solution:

1. **Understanding the Cannizzaro Reaction**: The Cannizzaro reaction occurs with aldehydes that do not have alpha-hydrogens. In this case, formaldehyde (HCHO) is an aldehyde that can undergo this reaction in the presence of a strong base.

2. **Setting Up the Reaction**: We will take formaldehyde and mix it with a concentrated solution of a strong base, such as sodium hydroxide (NaOH).
