Assertion : `O_(3)` and `NO_(2)^(-)` are isoelectronic.
Reason : Bond angle of `O_(3)` and `NO_(2)^(-)` are `118.8^(@)` and `115^(@)` respectively.

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 reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
b
Both are correct .The difference in bond angle is due to lone pair -bond pair repulsion in `O_(3)` and lone electron-bond pair repulsion in `NO_(2)^(-)`.
