AIIMS 2017 Chemistry Magnetic Properties Assertion Reason Question
In the following questions a statement of Assertion (A) followed by a statement of Reason (R) is given. Choose the correct answer out of the following choice.
Assertion (A) Superoxides of alkali metals are paramagnetic in nature.
Reason (R) Superoxide contain the ion which has one unpaired electron.
Both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
Both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.
Assertion is correct but Reason is incorrect.
Both Assertion and Reason are incorrect.
Correct Answer
Detailed Explanation
Superoxide (O₂⁻) indeed contains an unpaired electron, making it paramagnetic; however, the assertion that both statements are true is incorrect because the reason provided does not accurately explain the assertion. While the assertion about superoxide's paramagnetism is true, the reason is misleading as it implies a direct relationship that is not fully substantiated. Options A and B are incorrect because they assume both statements are true, while option C incorrectly states that the assertion is correct but the reason is not, failing to recognize that the reason itself is flawed. Understanding the electronic configuration of superoxide and its implications for magnetic properties is crucial in grasping these concepts.
