Which of the following is the correct structure of D.D.T.?

Options

A.
B.
C.
D.

Answer

To determine the correct structure of DDT (Dichlorodiphenyltrichloroethane), we will follow these steps:

### Step 1: Understand the Name
DDT stands for Dichlorodiphenyltrichloroethane. This name indicates that the compound has:
- Two phenyl (benzene) rings (dichloro means two chlorines are attached to the phenyl groups).
- A trichloroethane part, which means there are three chlorine atoms attached to an ethane structure.

**Hint:** Break down the name into its components to understand the structure better.

### Step 2: Identify the Ethane Backbone
The ethane part of DDT is the central structure. Ethane (C2H6) consists of two carbon atoms connected by a single bond. In DDT, one of these carbon atoms will have three chlorine atoms attached to it.

**Hint:** Visualize ethane as two carbon atoms connected by a single bond.

### Step 3: Add the Chlorine Atoms
For the trichloro part, we place three chlorine (Cl) atoms on one of the carbon atoms of the ethane. This gives us a carbon atom with three chlorine substituents.

**Hint:** Remember that the trichloro indicates three chlorine atoms on one carbon.

### Step 4: Attach the Phenyl Groups
Now, we need to add the two phenyl groups (C6H5) to the other carbon atom of the ethane. Each phenyl group will have two chlorine atoms attached to it (dichloro).

**Hint:** Each phenyl group is a benzene ring (C6H5), and you need to attach two chlorines to these rings.

### Step 5: Combine All Parts
Now, we can combine all the parts:
- One carbon with three chlorines (trichloro).
- The other carbon connected to two phenyl groups, each with two chlorines.

The final structure of DDT will look like this:

```
Cl
|
Cl - C - Cl
|
C6H4
|
C6H4
```

### Step 6: Identify the Correct Structure
After constructing the structure, compare it with the options provided in the question. The correct structure of DDT will match the one you have drawn.

**Hint:** Look for the option that has the two phenyl rings and the trichloroethane structure.

### Conclusion
The correct answer is option C, which represents the structure of DDT accurately.
