Vedclass · Answer

(B) The co-ordinate bond (dative bond) is a type of covalent bond where both electrons come from one atom.In $BH_4^-$,the $B-H$ bond formed by the reaction of $BH_3$ and $H^-$ is a co-ordinate bond.In $H_3O^{+}$,the $O-H$ bond formed by the reaction of $H_2O$ and $H^{+}$ is a co-ordinate bond.In $NH_4^{+}$,the $N-H$ bond formed by the reaction of $NH_3$ and $H^{+}$ is a co-ordinate 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. There is no dative bond involved in its resonance structures.Therefore,the correct option is $B$.
