In the following question, an Assertion (A) is followed by a corresponding Reason (R). Use the following keys to choose the appropriate answer.
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. : If both (A) and (R) are correct and (R) is the correct explanation of (A)., If both (A) and (R) are correct, but (R) is not the correct explanation of (A)., If (A) is correct, but (R) is incorrect., If both (A) and (R) are incorrect.

A

If both (A) and (R) are correct and (R) is the correct explanation of (A).

B

If both (A) and (R) are correct, but (R) is not the correct explanation of (A).

C

If (A) is correct, but (R) is incorrect.

D

If both (A) and (R) are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
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.
