Carbon is the least electronegative molecule and thus comes in the center. How many resonance structures can be drawn for the following molecule? Structure #1 is the most stable resonance Lewis structure since the octet rule is obeyed and the negative formal charge is carried out by N (electronegativity: 3.04) the most electronegative atom compared to S (electronegativity: 2.58). In many cases, a single Lewis structure fails to explain the bonding in a molecule/polyatomic ion due to the presence of partial charges and fractional bonds in it.
