Question

Which of the following orbitals lobe is not present at all either in the nodal plane of $p_x$ orbital ?

• A. $d_{xy}$
• B. $d_{yz}$
• C. $d_{x^2-y^2}$
• D. $p_z$

Answer 1

Answer: (A)

$d_{xy}$

The nodal plane of $p_x$ is y-z plane. Among the given options, $p_3$ & $d_{yz}$ have all its lobes in y-z plane, where as $d_{xy}$ has all its lobes perpendicular (out of this) plane. The $d_{x^2-y^2}$ orbital has $2$ lobes in the y-z plane. Hence answer of the question is $d_{xy}$ plane.
