Q. Assertion (A): In organic layer test, `Cl_2` water is added to the sodium extract, which oxidises `Br^(-)` and `I^(-)` ions to `Br_2` and`I_2`, respectively.
Reason (R): Reduction potential of `Cl_2` is greater than that of `Br_2` and `I_2`.

The correct Answer is:
To solve the question, we need to analyze both the Assertion (A) and the Reason (R) given in the problem. ### Step 1: Analyze the Assertion (A) Assertion (A) states: "In organic layer test, Cl₂ water is added to the sodium extract, which oxidizes Br⁻ and I⁻ ions to Br₂ and I₂, respectively." - The organic layer test is a qualitative analysis method used to identify halide ions in a sample. - When Cl₂ water is added to a sodium extract containing Br⁻ and I⁻ ions, the chlorine oxidizes these ions to their respective diatomic forms (Br₂ and I₂). - This statement is correct as chlorine is a stronger oxidizing agent than bromide and iodide ions. ### Step 2: Analyze the Reason (R) Reason (R) states: "Reduction potential of Cl₂ is greater than that of Br₂ and I₂." - The reduction potential indicates the tendency of a species to gain electrons (be reduced). A higher reduction potential means a stronger oxidizing agent. - The standard reduction potentials are as follows: - Cl₂ + 2e⁻ → 2Cl⁻ (E° = +1.36 V) - Br₂ + 2e⁻ → 2Br⁻ (E° = +1.07 V) - I₂ + 2e⁻ → 2I⁻ (E° = +0.54 V) - Since the reduction potential of Cl₂ is indeed greater than that of both Br₂ and I₂, this statement is also correct. ### Step 3: Determine the Relationship between (A) and (R) - Since both (A) and (R) are correct, and (R) provides the correct explanation for (A), we conclude that the correct answer is: **(a). If both (A) and (R) are correct and (R) is the correct explanation for (A).** ### Final Answer: The correct option is (a). ---
