Vedclass · Answer

(D) coordinate bond (or dative bond) is a type of covalent bond where both electrons come from the same atom.$1$. In $PH_4^+$,the $P$ atom donates a lone pair to an $H^+$ ion,forming a coordinate bond.$2$. In $NO_2$,the nitrogen atom forms a coordinate bond with one of the oxygen atoms to complete its octet.$3$. In $O_3$ (ozone),one oxygen atom forms a coordinate bond with another oxygen atom.$4$. In $CO_3^{2-}$,the structure consists of one $C=O$ double bond and two $C-O$ single bonds with resonance,involving only standard covalent bonds. There is no coordinate bond present.Therefore,the correct option is $D$.

Which of the following molecules does not have coordinate bonds?
