Question

Assertion : `F_(2)and O_(2)^(2-)`have bond order 1 while `N_(2),CO and NO^(+)` have bond order 3.
Reason : Higher the bond order, higher is the stability of the molecule.
A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason in not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Answer 1

Correct Answer - B
Isoelectronic molecules and ions have identical bond orders, `F_(2) and O_(2)^(2-)` are isoelectronic with 18 electrons each and `N_(2), CO and NO^(+)` are isoelectronic with 14 electrons each.
