Answer

To solve the question regarding the reaction of CH3NO2 with Cl2 and NaOH, we need to analyze the reaction step by step to determine which product is not obtained.

### Step-by-Step Solution:

1. **Identify the Reactants**: The reactants in the reaction are CH3NO2 (methyl nitro compound), Cl2 (chlorine gas), and NaOH (sodium hydroxide).

2. **Initial Reaction**: The NaOH acts as a base and abstracts a hydrogen atom from the CH3 group of CH3NO2. This results in the formation of CH2NO2 (methyl nitrite) and water (H2O).

\[ \text{CH}_3\text{NO}_2 + \text{NaOH} \rightarrow \text{CH}_2\text{NO}_2 + \text{H}_2\text{O} \]

3. **Chlorination Step**: The CH2NO2 can now react with Cl2. The chlorine will replace one of the hydrogen atoms, leading to the formation of CHClNO2 (chloromethyl nitro compound).

\[ \text{CH}_2\text{NO}_2 + \text{Cl}_2 \rightarrow \text{CHClNO}_2 + \text{HCl} \]

4. **Further Chlorination**: The reaction can continue as NaOH can abstract another hydrogen from CHClNO2, allowing for further chlorination. This leads to the formation of CCl2NO2 (dichloromethyl nitro compound).

\[ \text{CHClNO}_2 + \text{NaOH} \rightarrow \text{CCl}_2\text{NO}_2 + \text{H}_2\text{O} \]

5. **Final Product Formation**: Continuing this process, we can replace another hydrogen with chlorine, resulting in the formation of CCl3NO2 (trichloromethyl nitro compound).

\[ \text{CCl}_2\text{NO}_2 + \text{Cl}_2 \rightarrow \text{CCl}_3\text{NO}_2 + \text{HCl} \]

6. **Identify the Product Not Obtained**: The question specifically asks for the product that is **not** obtained in this reaction sequence. The product CHClNH2 (chloromethyl amine) is not formed during any of these steps, as the reaction primarily leads to the formation of chlorinated nitro compounds instead of amines.

### Conclusion:
The product that is **not obtained** in the reaction of CH3NO2 with Cl2 and NaOH is **CHClNH2**.
