Assertion: The covalence of nitrogen in N2O5 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

Structure of N2O5 is <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/e31d7b4444e0dc692f36d948c3fed3f2-.jpeg" /> Hence, it forms 4 covalent bonds with oxygen. It cannot expand its covalence beyond 4 due to the non-availability of d-orbital.

Q. Assertion : The covalence of nitrogen in $N_{2} O_{5}$ is $5$
Reason : Nitrogen can expand its covalence beyond $4$ .

If both assertion and reason are true and reason is the correct explanation of assertion

If both assertion and reason are true but reason is not the correct explanation of assertion

If assertion is true but reason is false

If both assertion and reason are false

Structure of $N_{2} O_{5}$ is

Hence, it forms $4$ covalent bonds with oxygen. It cannot expand its covalence beyond $4$ due to the non-availability of $d$ -orbital.
