Out of the following orbitals which have nodal plane perpendicular to the plane of orbital?

Solution:

The orbitals which have nodal plane perpendicular to the plane of orbital is $4d_{x^2-y^2}$

A nodal plane is the area surrounding the nucleus in the quantum mechanical model of the atom where there is almost no chance of finding an electron. The azimuthal quantum number is equal to the number of nodal planes in an orbital.
