Three resonance structures are possible for the thiocyanate ion, SCN⁻.
(a) Draw the three resonance structures.
(b) Calculate the formal charge on each atom in each resonance structure.
(c) Based on formal charges and electronegativity, predict which resonance structure most closely approximates the bonding in this ion?
(d) What are the similarities and differences of bonding in SCN⁻ compared to the bonding in OCN⁻ .
