Calculate the formal charges on the oxygen atoms labeled 1, 2, and 3 in the most stable resonance st — Chemical Bonding Chemistry Question
Question
Calculate the formal charges on the oxygen atoms labeled 1, 2, and 3 in the most stable resonance structure of ozone ($O_3$) arranged as $O_{(1)}=O_{(2)}-O_{(3)}$.
Answer: A
💡 Solution & Explanation
Formal Charge = Valence electrons - Non-bonding electrons - (Bonding electrons)/2. For $O_{(1)}$ (double bond): $6 - 4 - 4/2 = 0$. For $O_{(2)}$ (central): $6 - 2 - 6/2 = +1$. For $O_{(3)}$ (single bond): $6 - 6 - 2/2 = -1$.
