Question

Assertion (A): Molecular nitrogen is less reactive than molecular oxygen.

Reason (R): In molecular nitrogen two nitrogen atoms are joined by double bonds.

विकल्प

• If both A and R are true, and R is the correct explanation of A.

• If both A and R are true, but R is not the correct explanation of A.

• If A is true, but R is false.

• If both A and R are false.

Answer 1

If A is true, but R is false.

Explanation:

The assertion is entirely true because molecular nitrogen (N₂) is highly inert and less reactive than molecular oxygen (O₂) at room temperature due to its exceptionally high bond dissociation energy. However, the reason is completely false because the two nitrogen atoms in an N₂ molecule are actually held together by an exceptionally strong triple covalent bond (N ≡ N), not a double bond.
