Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Understanding Aniline Structure**: Aniline is an aromatic amine with the formula C6H5NH2. It consists of a benzene ring (C6H5) attached to an amino group (NH2). 2. **Nitration Reaction**: Nitration is the process of introducing a nitro group (NO2) into an organic compound, typically using a mixture of concentrated nitric acid (HNO3) and concentrated sulfuric acid (H2SO4). 3. **Effect of the Amino Group**: The amino group (NH2) is a strong activating group and is ortho/para directing in electrophilic aromatic substitution reactions. However, it can also be protonated under acidic conditions, leading to the formation of anilinium ion (C6H5NH3+). ...
