Question:

In each of the following question, a statement of Assertion (A) is given followed by a corresponding statement of Reason (R). Choose the correct answer as:

Assertion (A): P4 is more reactive than N2.

Reason (R): P—P single bond is much weaker compared to N≡N triple bond.

Options:

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

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

If the assertion is true, but the reason is false.

If both assertion and reason are false.

Correct Answer:

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

Explanation:

P4​ has angular strain and all single bonds which are relatively weaker than N2​(N≡N). Therefore phosphorous is more reactive.

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