Draw the structure of semicarbozone of methanal.

Explanation

To draw the structure of semicarbazone of methanal (formaldehyde), we need to follow a series of steps to understand the reaction between methanal and semicarbazide. Here’s a step-by-step solution:

### Step 1: Identify Methanal
Methanal, also known as formaldehyde, has the molecular formula HCHO. Its structure can be represented as:
```
