Answer

To solve the question, "When aniline is treated with benzene diazonium chloride at low temperature in a weakly acidic medium, the final product obtained is:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Reactants**:
- Aniline (C6H5NH2) is an amine where the amino group (-NH2) is attached to a benzene ring.
- Benzene diazonium chloride (C6H5N2Cl) is a compound where a diazonium group (N2+) is attached to a benzene ring.

2. **Identifying the Reaction Type**:
- The reaction between aniline and benzene diazonium chloride is an example of an electrophilic aromatic substitution reaction. In this reaction, the diazonium ion acts as the electrophile.

3. **Position of Electrophilic Attack**:
- Aniline is an ortho-para directing group due to the electron-donating nature of the amino group. This means that the electrophile (the diazonium ion) will preferentially attack the ortho or para positions of the aniline.

4. **Reaction Conditions**:
- The reaction is conducted at low temperature and in a weakly acidic medium. These conditions help to stabilize the diazonium ion and favor the substitution reaction without leading to further reactions or decomposition.

5. **Formation of the Product**:
- The diazonium ion (C6H5N2+) will attack the para position of the aniline, leading to the formation of a new compound. The product of this reaction will be para-aminobenzenesulfonic acid (C6H4(NH2)(N2+)), where the diazonium group replaces a hydrogen atom at the para position.

6. **Final Product**:
- The final product obtained from the reaction of aniline with benzene diazonium chloride at low temperature in a weakly acidic medium is para-aminobenzenesulfonic acid.

### Conclusion:
Thus, the final product obtained is para-aminobenzenesulfonic acid.
