Which from following d-orbitals has different shape as compared with others?
- A$\mathrm{d} x \mathrm{y}$
- B$\mathrm{d} y \mathrm{z}$
- C$\mathrm{d} x \mathrm{z}$
- Correct answerD$\mathrm{dz}^2$
Solution
The five $d$-orbitals are designated as $d_{xy}$, $d_{yz}$, $d_{xz}$, $d_{x^2-y^2}$, and $d_{z^2}$.
Orbitals $d_{xy}$, $d_{yz}$, and $d_{xz}$ all exhibit the characteristic cloverleaf shape, with lobes oriented between their respective axes.
Orbital $d_{z^2}$ possesses a distinct geometry, featuring two primary lobes aligned along the $z$-axis and a toroidal region in the $xy$-plane.
Consequently, $d_{z^2}$ is structurally dissimilar to the other three orbitals.
The orbital with a different shape is $\boxed{D}$.
Hence, the correct answer is option: 'D'.
