Question

Assertion (A) `N_(2)` is less reactive than `P_(4)`.
Reason (R ) Nitrogen has more electron gain enthalpy then phosphorus.
A. Both Assertion and Reason are correct statements , and Reason is the correct explation of the Assertion.
B. Both Assertion and Reason are correct statements , and Reason is not the correct explanation of the Assertion.
C. Assertion is correct, but Reason is wrong statement.
D. Assertion is wrong but Reason is correct statement.

Answer 1

Assertion is true, but reason is false.
`N_(2)` is less reactive than `P_(4)` due to high value of bond dissociation energy which is due to presence of triple bond between two N - atoms of `N_(2)` molecule.
