$ClO_3$

Vedclass · Answer

(B) To determine the bond order $(B.O.)$,we use the formula: $B.O. = \frac{	ext{Total number of bonds}}{	ext{Total number of resonating structures}}$ or by analyzing the number of $Cl-O$ bonds in the Lewis structure.$A) \, ClO_3^-$: The structure has $3$ oxygen atoms and $5$ bonds total (one double bond,two single bonds),$B.O. = \frac{5}{3} \approx 1.66$.$B) \, ClO_3$: The neutral radical $ClO_3$ has $3$ oxygen atoms and $6$ bonds total (three double bonds),$B.O. = \frac{6}{3} = 2.0$.$C) \, ClO_2$: The neutral radical $ClO_2$ has $2$ oxygen atoms and $3$ bonds total (one double bond,one single bond),$B.O. = \frac{3}{2} = 1.5$.$D) \, ClO_2^-$: The structure has $2$ oxygen atoms and $3$ bonds total (one double bond,one single bond),$B.O. = \frac{3}{2} = 1.5$.Comparing the values,$ClO_3$ has the maximum bond order of $2.0$.

The species having the maximum $Cl-O$ bond order is:
