Assertion : N(2) is less reactive than P...

Assertion : `N_(2)` is less reactive than `P_(4)`.
Reason : Nitrogen has more electron gain enthalpy than phosphorus.

A

Both assertion and reason are correct statements, and reason is the correct explanation of the assertion.

B

Both assertion and reason are correct statements, but reason is not the correct explanation of the assertion.

C

Assertion is correct, but reason is wrong statement.

D

Both assertion and reason are wrong statement.

Text Solution

Verified by Experts

The correct Answer is:
C
Correct reason. P-P single bond in `P_(4)` molecules is much weaker (213 kJ `mol^(-1)`) than N = N triple bond (341.4 kJ `mol^(-1)`) in `N_(2)`.
