A

If both `(A)` and `(R )` are correct and `(R )` is the correct explanation of `(A)`.

B

If both `(A)` and `(R )` are correct but `(R )` is not the correct explanation of `(A)`.

C

If `(A)` is correct but `(R )` is incorrect.

D

If `(A)` and `(R )` are incorrect.

The correct Answer is:
To solve the problem, we need to analyze the assertion and reason provided in the question. ### Step 1: Analyze the Assertion The assertion states that a reaction occurs between Fe and I2, but no reaction occurs between Fe²⁺ and I⁻. - The reaction between Fe (iron) and I2 (iodine) can be represented as: \[ 2Fe + I_2 \rightarrow 2Fe^{2+} + 2I^- \] This reaction occurs because Fe can lose electrons (it gets oxidized) and I2 can gain electrons (it gets reduced). - The second part of the assertion states that there is no reaction between Fe²⁺ and I⁻. This can be understood by considering the standard reduction potentials. Fe²⁺ is already in a higher oxidation state and cannot further reduce I⁻ (which is already in its reduced form). ### Step 2: Analyze the Reason The reason states that Fe is a better reducing agent than I⁻. - A reducing agent is a substance that donates electrons in a chemical reaction and gets oxidized in the process. - In this case, Fe (in its elemental form) can readily donate electrons to I2, making it a strong reducing agent. - On the other hand, I⁻ is already in a reduced state and cannot act as a reducing agent to reduce Fe²⁺ further. ### Step 3: Conclusion Both the assertion and reason are correct: - The assertion is correct because the reaction between Fe and I2 occurs, while the reaction between Fe²⁺ and I⁻ does not occur. - The reason is also correct because Fe is indeed a better reducing agent than I⁻. Thus, the correct answer is that both the assertion and reason are true, and the reason correctly explains the assertion. ### Final Answer Both assertion (A) and reason (R) are correct, and the reason is the correct explanation of the assertion. ---
