Question

Which of the following element forms $p_{\pi} - p_{\pi}$ bond with itself ?

• A. N
• B. P
• C. Se
• D. Te

Answer 1

Answer: (A)

N

Answer 2

Nitrogen, being smaller in size can effectively from $p \pi-p \pi$ bonds with other atoms of itself and atoms of other elements with small size and high electronegativity such as oxygen and carbon. The other elements do not from $p \pi-p \pi$ bonds because of their relatively lager size.

In other words the $p$ orbital of there elements are larger in size.
