$SO_3^{2-}$

Vedclass · Answer

(B) In $SO_3^{2-}$ (sulfite ion),the central sulfur atom has an oxidation state of $+4$ and its valence shell configuration is $3s^2 3p^4$. Sulfur forms three $S-O$ sigma bonds using $sp^3$ hybridization. One lone pair is present on sulfur. The remaining $3d$ orbitals of sulfur overlap with the $2p$ orbitals of oxygen to form $p \pi - d \pi$ bonds. In $NO_3^-$,$BO_3^{3-}$,and $CO_3^{2-}$,the central atoms $(N, B, C)$ belong to the second period and do not have $d$-orbitals available for bonding,so they only exhibit $p \pi - p \pi$ bonding.

Which of the following contains $p \pi - d \pi$ bonding?
