Question

Assertion:

${\text{P}}_4$ is more reactive than ${\text{N}}_2$.

Reason:

$\text{P - P}$ bonds are relatively weaker than $\text{N - N}$.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

$P_4$ has angular strain and all single bonds which are relatively weaker than $N_2(N\equiv N)$. Therefore phosphorous is more reactive.

Thus, Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Hence, the correct option is $\text{A}$
