Interpretation Introduction

To determine: The correct Lewis structure for $C{O}_3^{2-}.$

a) ${\left[{}_{•}^{•}\stackrel{••}{O}==\stackrel{\stackrel{••}{{}_{•}^{•}O}}{\stackrel{\parallel }{C}}=={\stackrel{••}{O}}_{•}^{•}\right]}^{2-}$

b) ${\left[{}_{•}^{•}\stackrel{••}{\underset{••}{O}}--\stackrel{\stackrel{••}{{}_{•}^{•}O}}{\stackrel{\parallel }{C}}-{\stackrel{••}{-O}}_{•}^{•}\right]}^{2-}\stackrel{}{\leftrightarrow }{\left[\stackrel{••}{{}_{•}^{•}O}==\stackrel{{}_{•}^{•}\stackrel{••}{O_{•}^{•}}}{\stackrel{|}{C}}--\stackrel{••}{{\underset{••}{O}}_{•}^{•}}\right]}^{2-}\underset{}{\leftrightarrow }{\left[\stackrel{••}{\underset{••}{{}_{•}^{•}O}}--\stackrel{{}_{•}^{•}\stackrel{••}{O_{•}^{•}}}{\stackrel{|}{C}}=={\stackrel{••}{=O}}_{•}^{•}\right]}^{2-}$

c) ${\left[{}_{•}^{•}\stackrel{••}{\underset{••}{O}}--\stackrel{\stackrel{••}{{}_{•}^{•}{O}_{•}^{•}}}{\stackrel{|}{\underset{••}{C}}}--{\stackrel{••}{\underset{••}{O}}}_{•}^{•}\right]}^{2-}$

d) ${\left[\underset{••}{\stackrel{••}{{}_{•}^{•}O}}--\stackrel{••}{C}==\stackrel{••}{O}--\stackrel{••}{\underset{••}{O}}{}_{•}^{•}\right]}^{2-}$
