Vedclass · Answer

(C) The correct answer is $(C)$.For an orbital to have zero probability of finding an electron in the $XY$ plane,the $XY$ plane must be a nodal plane for that orbital.$1$. For $3p_z$,the nodal plane is the $XY$ plane (since the electron density is along the $z$-axis).$2$. For $4d_{xz}$,the nodal planes are the $XY$ plane and the $YZ$ plane (since the lobes lie in the $XZ$ plane).$3$. Therefore,in the pair $(4d_{xz}, 3p_z)$,both orbitals have the $XY$ plane as a nodal plane,meaning the probability of finding an electron in the $XY$ plane is zero for both.

In which of the following pairs of orbitals is the probability of finding the electron zero in the $XY$ plane?
