Unformatted text preview: 2 in next (+2, -1), NaCl, NaF are the same and lowest charges. NaF is greater than NaCl because F- is smaller than Cl-5. (5 points) Specify the formal charges on each atom in each resonance structure below for [OCSN] 3-and circle the most stable resonance structure. The electronegativities for S and N are 2.5 and 3.0, respectively. (a) C S O N : : .. .. .. .. : ..
