Question

The anomalous behaviour of nitrogen is due to:

• A. small size and high electronegativity
• B. non availability of d-orbitals in valency shell
• C. ease of multiple bond formation
• D. all are correct

Answer 1

The correct option is D all are correct

Nitrogen differs from other members of the group due to its smaller size, high electronegativity, high IE and non availability of d-orbitals. Nitrogen has unique ability to form $p\pi -p\pi$ multiple bonds with itself and with other elements having small size and high electronegativity.
