Question

Directions : In the following questions, A statement of Assertion (A) is followed by a statement of
Reason (R). Mark the correct choice as.

Assertion (A) : $N_2$ is less reactive than $P_{4.}$
Reason (R) : Nitrogen has more electron gain enthalpy than phosphorus.

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but R is NOT the correct explanation of A
• C. A is true but R is false
• D. A is false and R is True

Answer 1

The correct option is C A is true but R is false

Due to high bond dissociation energy of tripe bond between the two N atoms, nitrogen (N) is less reactive than $P_4$ and its electron gain enthalpy is less than phosphorus.
