Assertion (A) N(2) is less reactive than...

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.

Text Solution

Verified by Experts

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.
