Assertion : Molecular nitrogen is less reactive than molecular oxygen.
Reason : The bond length of is shorter than that of oxygen.
Options
- AIf both assertion and reason are true and reason is the correct explanation of the assertion
- BIf both assertion and reason are true but reason is not the correct explanation of the assertion
- CIf assertion is true, but reason is false
- DBoth assertion and reason are false statements.
Correct answer
A. If both assertion and reason are true and reason is the correct explanation of the assertion
Step-by-step solution
Bond order of , bond order of . Higher the bond order, higher is the bond dissociation energy. i.e. higher stability or less reactivity. Thus is less reactive than . Higher the bond order, shorter is the bond length. Shorter bond length of shows its higher bond order.
