Vedclass · Answer

(B) If the molecular axis is the $x-$axis,then the $\pi-$ bond is formed by the lateral overlap of orbitals perpendicular to this axis,such as $p_y$ or $p_z$ orbitals.For the strongest $\pi-$ bond,the overlap should involve orbitals with the same principal quantum number and effective spatial orientation.$2p_x + 2p_x$ results in a $\sigma-$ bond because the orbitals are oriented along the molecular axis.$2p_y + 2p_y$ results in a $\pi-$ bond with effective overlap due to the same principal quantum number $(n=2)$.$2p_y + 3d_{xy}$ and $2p_z + 4p_z$ involve orbitals with different principal quantum numbers,leading to weaker overlap compared to $2p_y + 2p_y$.

Which of the following would result in the formation of the strongest $\pi-$ bond if the molecular axis is the $x-$axis?
