Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
Assertion: Molecular nitrogen is less reactive than molecular oxygen. Reason: The bond length of \[{{N}_{2}}\] is shorter than that of oxygen.A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but the reason is not the correct explanation of the assertion.
C) If assertion is true statement but reason is false.
D) If both assertion and reason are false.
Correct Answer: B
Solution :
Molecular nitrogen is less reactive than that of oxygen because nitrogen has high dissociation energy in comparison to oxygen so, its reactivity is less. Also bond length of nitrogen is shorter than oxygen because of presence of triple bond between nitrogen atoms. So both are true but not correct explanation.
