Question

Nitrogen has unique ability to form $P\pi -P\pi$ multiple bonds with itself and with other elements due to:

• A. small size and low electronegativity
• B. large size and high electronegativity
• C. large size and low electronegativity
• D. small size and high electronegativity

Answer 1

Answer: (D)

small size and high electronegativity

Nitrogen has unique ability to form $P\pi -P\pi$ multiple bonds with itself and with other elements due to small size and high electronegativity. The inner core of nitrogen contains only 1s electrons. There is no repulsion between non bonded electrons of inner core. Hence p orbitals easily overlap to form pi bonds.
