Pz Sigma Bond

Postby Jedrick Zablan 3L » Wed Nov 20, 2019 9:33 pm

Hello! Why does Pz form a sigma bond while the other p orbitals form a pi bond?

Sigma bonds occur when two orbital overlap end to end. Pi bonds form when two orbitals overlap side by side. S and p orbitals can form sigma bonds; however, since there can be 3 p orbitals (Pz, Py, Pz) in a p subshell, only one can have a sigma bond. Therefore, only one of the p orbitals is oriented around the internuclear axis, which is Pz because it coincides with the internuclear axis/z-axis.
