Transcript: Let's do the ClO2- Lewis structure. In thecourse of these reactions, the ClO2 is itself reduced. This is a better structure because the formal charges are closer to zero while still retaining that negative one right there. -. Draw The Lewis Structure For ClO2- Ion. Wiki User Answered . Also ClO2^- is not an Arrhenius base because it does not dissolve in water to liberate a hydroxide ion. Using chlorine dioxide minimizes the amount of toxic organochlorine compounds that are produced as byproducts. See the answer. Chlorine's the least electronegative, it goes in the center. So this looks pretty good. Except that chlorite ion is bent at about 109.5 degrees since there are two lone pairs on Cl and the ion has tetrahdral (sp3) electron pair geometry. The molecular geometry of ClO2 is a bent or V-shape, according to Bristol ChemLabS. The following comparisons show what happens when chlorine dioxide reacts. … Since there are two lone pairs on chlorine, the electron pair repulsion will result in a bond angle that is slightly less than 109.5. Remember to put brackets around the Lewis structure, along with a negative sign, to show that it is an ion.
