Conversion of Toluene into p-nitrobenzyl ethyl ether

Explanation

To convert toluene into para-nitro-benzyl ethyl ether, we can follow these steps:

### Step 1: Nitration of Toluene
- **Reaction**: Toluene (C6H5CH3) is treated with a mixture of concentrated nitric acid (HNO3) and concentrated sulfuric acid (H2SO4) to introduce a nitro group (-NO2) onto the aromatic ring.
- **Products**: This reaction will yield two isomers: para-nitrotoluene and ortho-nitrotoluene. However, due to steric factors, the para isomer is usually favored.

### Step 2: Bromination of Para-Nitrotoluene
- **Reaction**: The para-nitrotoluene is then treated with N-bromo-succinimide (NBS) in the presence of light or heat.
