Question:
Which of the following is correct mixture of azeotrope?
Which of the following is correct mixture of azeotrope?
Show Hint
Azeotropes are mixtures where the vapor has the same composition as the liquid, and they cannot be separated by simple distillation.

- Chlorobenzene + bromobenzene
- \( \text{C}_2\text{H}_5\text{Br} + \text{C}_2\text{H}_5\text{Cl} \)
- \( \text{C}_6\text{H}_{14} + \text{C}_7\text{H}_{16} \)
- \( \text{CCl}_4 + \text{CHCl}_3 \)

The Correct Option is D
Solution and Explanation
An azeotrope is a mixture of two or more liquids that has the same composition in both the liquid and vapor phases, making it impossible to separate them by simple distillation. The correct azeotrope here is formed by carbon tetrachloride (\(CCl_4\)) and chloroform (\(CHCl_3\)), which forms an azeotropic mixture. This mixture has a constant boiling point, unlike most mixtures that boil at different points. - Chlorobenzene + Bromobenzene and \(C_2H_5Br\) + \(C_2H_5Cl\) do not form azeotropes.
- \(C_6H_14\) + \(C_7H_16\) are alkane hydrocarbons that do not form an azeotropic mixture.
Therefore, the correct answer is \(CCl_4\) + \(CHCl_3\), as they form a true azeotrope.
