Question

which of the following pairs of D orbitals will have electron density along the axe

​

Answer 1

⇒Each d-orbital has 4 lobes . In dxy orbital the lobes are placed in between  x and y axes . similarly in dzx and dyz.

In dz² orbital, two lobes lie on z axis and there is a ring of electron -cloud around the centre.

In dx²-y² orbital, the lobes lie on x and y axes.

Each d orbital has two nodal planes.
