Among the following solutions, the one capable of forming azeotropic mixtures is:

Options

A. `CCl_(4) + CHCl_(3)`
B. `C_(6)H_(14) + C_(7)H_(16)`
C. `C_(2)H_(5)Br + C_(2)H_(5)Cl`
D. chlorobenzene + bromobenzene

Answer

To determine which solution is capable of forming azeotropic mixtures, we need to understand the concept of azeotropes and the nature of the solutions provided in the options.

### Step-by-Step Solution:

1. **Understanding Azeotropic Mixtures**:
- Azeotropic mixtures are solutions that have a constant boiling point and maintain the same composition in both the liquid and vapor phases during boiling. This means that they cannot be separated into their components by simple distillation.

2. **Types of Solutions**:
- Solutions can be classified into two categories: ideal and non-ideal solutions.
- **Ideal Solutions**: These obey Raoult's law, meaning that the interactions between different molecules are similar to those between like molecules. An example is the mixture of benzene and toluene.
- **Non-Ideal Solutions**: These do not obey Raoult's law due to significant differences in molecular structure, leading to different interactions. Non-ideal solutions are more likely to form azeotropes.

3. **Analyzing the Given Options**:
- We need to identify which of the given solutions are non-ideal:
- **Option 1**: Carbon Tetrachloride (CCl4) and Chloroform (CHCl3) - These two have different molecular structures and are likely to form a non-ideal solution.
- **Option 2**: Hexane (C6H14) and Heptane (C7H16) - These are both alkanes with similar structures, hence they form an ideal solution.
- **Option 3**: Bromoethane (C2H5Br) and Chloroethane (C2H5Cl) - These have similar structures and are also considered an ideal solution.
- **Option 4**: Chlorobenzene (C6H5Cl) and Bromobenzene (C6H5Br) - These compounds have similar structures and interactions, thus forming an ideal solution.

4. **Conclusion**:
- Among the options, only **Carbon Tetrachloride and Chloroform** (Option 1) are capable of forming an azeotropic mixture due to their non-ideal nature.

### Final Answer:
The solution capable of forming azeotropic mixtures is **Option 1: Carbon Tetrachloride and Chloroform**.
