Question

Explain hybridization of central atom in :$C{O}_3^{2-}$

Answer 1

Identify central atom

Hybridisation $=\frac{1}{2}$ (Valence electrons $+$ No. of monovalent atoms $-$ cationic charge $+$ anionic charge)

For ${CO}_3^{-2}$

$=\frac{1}{2}[4+0-0+2]=\frac{6}{2}=3={SP}^2$

Ans :- ${sp}^2$ hybridisatrion.
