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 of the given solutions is capable of forming azeotropic mixtures, we need to analyze each pair based on their characteristics as ideal or non-ideal solutions.

### Step-by-Step Solution:

1. **Understanding Azeotropic Mixtures**:
- An azeotropic mixture is a mixture of two or more liquids that has a constant boiling point and composition throughout the distillation process. The vapor produced has the same composition as the liquid mixture.

2. **Identifying Ideal vs Non-Ideal Solutions**:
- **Ideal Solutions**: These solutions follow Raoult's Law, where the interactions between different molecules are similar to those between like molecules. They usually consist of components with similar structures.
- **Non-Ideal Solutions**: These solutions do not follow Raoult's Law and typically involve components with different structures and interactions.

3. **Analyzing Each Option**:
- **TCl4 + CHCl3 (Carbon Tetrachloride + Chloroform)**: These two compounds have different structures and interactions, making them a non-ideal solution. Therefore, they can form an azeotropic mixture.
- **C6H14 + C7H16 (Hexane + Heptane)**: Both are alkanes with similar structures and interactions, making them an ideal solution. They do not form azeotropic mixtures.
- **C2H5Br + C2H5Cl (Bromoethane + Chloroethane)**: These compounds are also similar in structure and interactions, classifying them as an ideal solution. They do not form azeotropic mixtures.
- **Chlorobenzene + Bromobenzene**: These compounds are similar in structure, thus they are also considered an ideal solution and do not form azeotropic mixtures.

4. **Conclusion**:
- The only pair that can form an azeotropic mixture is **TCl4 + CHCl3 (Carbon Tetrachloride + Chloroform)**.

### Final Answer:
**TCl4 + CHCl3 (Carbon Tetrachloride + Chloroform)** is the solution capable of forming azeotropic mixtures.
