Question

The incorrect statement(s) among the following is (are):

• A. All d-orbitals including $d{z}^2$ possesses angular nodes.
• B. $d_{x^2-y^2}$ and $d_{z^2}$ orbitals lie in between the axis
• C. The degeneracy of p-orbital remains unaffected in a homogeneous external magnetic field
• D. All the d orbitals have four lobes of electron density, except for the $d_z^2$ orbital

Answer 1

The correct option is B $d_{x^2-y^2}$ and $d_{z^2}$ orbitals lie in between the axis

(a) All d-orbitals including $d{z}^2$ possesses angular nodes.

(b) B is incorrect, both the mentioned orbitals ($d_{z^2-y^2}$ and $d_z^2$ ) lies along the axis. . Orbitals $d_{xy},d_{yz}{d}_{zx}$ in between the axis.

(c) The degeneracy of p-orbital remains unaffected in a homogeneous external magnetic field .

(d) All the d orbitals have four lobes of electron density, except for the $d_z^2$ orbital. which has two opposing lobes and a doughnut of electron density around the middle.
