Problem: What are the formal charges on the sulfur (S), carbon (C), and nitrogen (N) atoms, respectively, in the resonance structure that contributes most to the stability of the thiocyanate ion, SCN−? The possible resonance structures for the thiocyanate ion, SCN−, areExpress your answers as integers separated by commas.The interactive activity shows how to calculate the formal charge of atoms in a structure. These formal charges can be used to predict the resonance structure that contributes most to the stability of a molecule or ion. The structure with the lowest formal charge on each atom and which places the negative charge on the most electronegative atom is generally the most stable.
