The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided: ### Step 1: Analyze the Assertion - **Assertion**: "Lithium is the weakest reducing agent among alkali metals." - **Evaluation**: This statement is incorrect. Lithium is actually the strongest reducing agent among alkali metals. This is due to its small size and high charge density, which leads to high hydration energy. ### Step 2: Analyze the Reason - **Reason**: "In alkali metals, ionization potential increases down the group." - **Evaluation**: This statement is also incorrect. In alkali metals, as we move down the group, the ionization potential actually decreases. This is because new electron shells are added as we go down the group, which places the outermost electron further from the nucleus, making it easier to remove. ### Step 3: Conclusion - Since both the assertion and the reason are false, the correct answer to the question is that both statements are incorrect. ### Final Answer: Both the assertion and the reason are false statements. ---
