MCQ
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.
  • ✓
    All are correct.
✓

Answer

Correct option: 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 $\text{p}\pi-\text{p}\pi$ multiple bonds with itself and with other elements having small size and high electronegativity.
