The formal charge on the sulfur atom in the resonance structure of sulfur dioxide which has one single bond and one double bond is
A) -2.
B) -1.
C) 0.
D) +1.
E) +2.

Question

Quizplus · Accepted Answer

The formal charge is calculated as: (Valence electrons of sulfur) - (Non-bonding electrons) - (Bonding electrons/2). For sulfur in SO2 with one single bond and one double bond: 6 - 4 - (4/2) = +1.
