What are the formal charges on the sulfur (SS), carbon (CC), and nitrogen (NN) atoms, respectively, in the resonance structure that contributes most to the stability of the thiocyanate ion, SCN−SCN−?

The formal charges of sulfur (S), carbon (C) and nitrogen (N) atoms in SCN⁻ are (-1), 0 and 0, respectively.

Explanation:

At first, let us consider the formula to calculate formal charge as follows:

Formal Charge = Valence electrons - Unbonded electrons - Bonded electrons

According to the structure of [S-C≡N]⁻,

The formal charges of S, C and N are as follows:

S = 6 - 6 - = -1

C = 4 - 0 - = 0

N = 5 - 2 - = 0

So, the formal charges of sulfur (S), carbon (C) and nitrogen (N) atoms in SCN⁻ are (-1), 0 and 0, respectively.
