Assertion : The covalence of nitrogen in...

Assertion : The covalence of nitrogen in `N_(2)O_(5)` is 5
Reason : Nitrogen can expand its covalence beyond 4.

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 is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
Structure of `N_(2)O_(5)` is

Hence, it forms 4 covalent bonds with oxygen. It cannotexpand its covalence beyond 4 due to the non-availabilityof d-orbital.
