Question

Assertion (A): Carbon reduces the oxides of Sodium and Magnesium.

Reason (R): Sodium and Magnesium have more affinity for Oxygen than Carbon.

Options

• Both (A) and (R) are true and (R) is the correct explanation of (A).

• Both (A) and (R) are true, but (R) is not the correct explanation of (A).

• (A) is true, but (R) is false.

• (A) is false, but (R) is true.

Answer 1

(A) is false, but (R) is true.

Explanation:

• Assertion (A) is false because carbon cannot reduce the oxides of very reactive metals like sodium (Na) and magnesium (Mg). These metals are higher than carbon in the reactivity series.
• Reason (R) is true because sodium and magnesium have a greater affinity for oxygen than carbon, which is why their oxides are very stable and cannot be reduced by carbon.
