Explanation

To solve the problem of what product is formed when trichloroacetaldehyde reacts with chlorobenzene in the presence of sulfuric acid, we can follow these steps:

### Step 1: Identify the Reactants
We have the following reactants:
- Trichloroacetaldehyde (CCl3CHO)
- Chlorobenzene (C6H5Cl)
- Sulfuric acid (H2SO4)

### Step 2: Understand the Reaction Conditions
Sulfuric acid acts as a dehydrating agent in this reaction. This means it will facilitate the removal of water from the reactants during the reaction process.

### Step 3: Reaction Mechanism
1. **Formation of an Electrophile**: The carbonyl carbon of trichloroacetaldehyde is electrophilic due to the presence of the electronegative chlorine atoms. This makes it susceptible to nucleophilic attack.
2. **Nucleophilic Attack**: Chlorobenzene can act as a nucleophile. The chlorine atom in chlorobenzene can attack the carbonyl carbon of trichloroacetaldehyde.
3. **Formation of DDT**: The reaction proceeds with the formation of a compound where the trichloroacetaldehyde is converted into a compound with two chlorobenzene groups attached. The sulfuric acid helps in the dehydration process, leading to the formation of DDT (Dichloro-Diphenyl-Trichloroethane).

### Step 4: Write the Product Structure
The product formed from this reaction is:
- The structure of DDT can be represented as:
- CCl3 (from trichloroacetaldehyde)
- Two phenyl groups (from chlorobenzene)
- The overall structure will be CCl3-C6H4-Cl-C6H4-Cl.

### Step 5: Final Product Confirmation
The final product of the reaction is DDT, which is represented as:
- C14H9Cl5 (Dichloro-Diphenyl-Trichloroethane).

### Conclusion
Thus, the product formed when trichloroacetaldehyde reacts with chlorobenzene in the presence of sulfuric acid is DDT.
