Write the structure formula of p-Nitrobenzaldehyde,

Explanation

To write the structural formula of p-Nitrobenzaldehyde, we will follow these steps:

### Step 1: Understand the Components
- **Benzaldehyde**: This is the base structure we need to start with. Benzaldehyde consists of a benzene ring (C6H5) attached to a formyl group (-CHO).

### Step 2: Draw the Benzene Ring
- Begin by drawing a hexagonal shape to represent the benzene ring. Each vertex of the hexagon represents a carbon atom, and the alternating double bonds can be represented by drawing a circle inside the hexagon or by showing the double bonds explicitly.
