Question

Quizplus · Accepted Answer

In the given resonance structure of sulfur dioxide (SO2), sulfur forms one single bond and one double bond with oxygen atoms. The formal charge is calculated as: Formal charge = Valence electrons - (Non-bonding electrons + 1/2 Bonding electrons). Sulfur has 6 valence electrons, 2 non-bonding electrons, and 3 bonding pairs (1 single bond + 1 double bond). Thus, the formal charge is 6 - (2 + 3) = +1.
