Vedclass · Answer

(C) coordinate covalent bond (dative bond) is formed when one atom donates a lone pair of electrons to another atom.In $BH_4^-$,the $BH_3$ molecule accepts a hydride ion $(H^-)$ to form the bond,which is a coordinate bond.In $NH_4^+$,the lone pair on nitrogen in $NH_3$ is donated to an $H^+$ ion,forming a coordinate bond.In $H_3O^+$,the lone pair on oxygen in $H_2O$ is donated to an $H^+$ ion,forming a coordinate bond.In $CO_3^{2-}$,the structure consists of one $C=O$ double bond and two $C-O$ single bonds with formal charges on oxygen atoms. All bonds are covalent,and there is no dative (coordinate) bond involved in the standard Lewis structure representation.
