Q. Identify the incorrect statements from the following.
A) The shapes of $d_{xy}$, $d_{yz}$, and $d_{zx}$ orbitals are similar to each other; and $d_{x^2-y^2}$ and $d_{z^2}$ are similar to each other.
B) All the five 5d orbitals are different in size when compared to the respective 4d orbitals.
C) All the five 4d orbitals have shapes similar to the respective 3d orbitals.
D) In an atom, all the five 3d orbitals are equal in energy in free state.
Explanation
[Solution] $d_{x^2-y^2}$ has four lobes along the axes, while $d_{z^2}$ has two lobes along z with a doughnut-shaped ring, so their shapes are not similar. Answer (1).
