Question

Which of the following orbital combination does not form $\pi$-bond?

• A. $p_x+p_x$ sideways overlapping
• B. $d_{x^2-y^2}+p_y$ sideways overlapping
• C. $d_{xy}+d_{xy}$ sideways overlapping
• D. $d_{yz}+p_y$ sideways overlapping

Answer 1

Answer: (B)

$d_{x^2-y^2}+p_y$ sideways overlapping

$d_{x^2-y^2}+p_y$ sideways overlapping does not form $\pi$-bond as the two orbitals do not have proper orientation for the overlap.
