Question

The orbitals that do not have planar nodes among the following is:

• A. $d_{xy}$
• B. $d_{x^2-y^2}$
• C. $d_{z^2}$
• D. All of the above

Answer 1

The correct option is C $d_{z^2}$

$d_{z^2}$ orbital has a doughnut rolled around the middle of the dumbbell. Hence, it has probability density along all the three axes and it has cone shaped node.
