The correct Answer is:
To solve the question, we will analyze both the assertion and the reason step by step. ### Step 1: Analyze the Assertion The assertion states that "Nitrogen is less reactive than molecular oxygen." - **Explanation**: Nitrogen (N₂) has a triple bond (N≡N) between the nitrogen atoms, while molecular oxygen (O₂) has a double bond (O=O). Triple bonds are generally stronger and more stable than double bonds. Therefore, nitrogen is less likely to react compared to oxygen, which can react more readily due to its weaker bond. ### Step 2: Analyze the Reason The reason states that "Bond length of N₂ is shorter than that of oxygen." - **Explanation**: The bond length is inversely related to bond strength; shorter bonds are typically stronger. Since N₂ has a triple bond, its bond length is shorter than the bond length of O₂, which has a double bond. This indicates that the bond in N₂ is stronger and requires more energy to break compared to the bond in O₂. ### Step 3: Connect Assertion and Reason Now, we need to determine if the reason provided is a correct explanation for the assertion. - **Explanation**: The reason correctly explains why nitrogen is less reactive than oxygen. The shorter bond length of N₂ (triple bond) compared to O₂ (double bond) implies that nitrogen is more stable and less reactive. Therefore, the reason supports the assertion. ### Conclusion Both the assertion and the reason are true, and the reason is indeed the correct explanation for the assertion. ### Final Answer Both the assertion and reason are true, and the reason is the correct explanation for the assertion. ---
