Answer

To determine the structure of 4-Nitro-N,N-Dimethylbenzenamine, we can break down the name into its components and construct the molecular structure step by step.

### Step-by-Step Solution:

1. **Identify the Base Structure**:
- The name indicates that we have a benzene ring. Benzene is a six-carbon aromatic ring with alternating double bonds.

2. **Add the Amine Group**:
- The term "benzenamine" indicates that there is an amine group (-NH2) attached to the benzene ring. The amine group is typically attached to one of the carbon atoms of the benzene ring.

3. **Position of the Amine Group**:
- The "4-" prefix indicates that the amine group is located at the para position (the 4th carbon) relative to the nitro group that will be added later.

4. **Add the Nitro Group**:
- The "4-Nitro" indicates that there is a nitro group (-NO2) also attached to the benzene ring at the para position (4th carbon) from the amine group. Since the amine group is at position 4, the nitro group will be at position 1.

5. **Add the Dimethyl Groups**:
- The "N,N-Dimethyl" indicates that there are two methyl groups (-CH3) attached to the nitrogen atom of the amine group. This means that instead of a simple -NH2 group, we have -N(CH3)2.

6. **Final Structure**:
- Now, we can put all these components together:
- Start with a benzene ring.
- Place the nitro group at position 1.
- Place the dimethyl amine group at position 4.

The final structure of 4-Nitro-N,N-Dimethylbenzenamine can be represented as follows:

```
NO2
|
C6H4-N(CH3)2
