Question

Which of the following d orbitals is not used in bonding to form $H_{2}S{O}_4$ ?

• A. $d_{xy}$
• B. $d_{yz}$
• C. $d_{zx}$
• D. $d_{z^2}$

Answer 1

The correct option is D $d_{z^2}$

$H_{2}S{O}_4$ has $s{p}^3$ hybridization, d orbitals are used only in $\pi$ bond formation and $d_{z^2}$ cannot be used in $\pi$ bond formation with p orbital of O atom.
