It is prepared on massive scales as a precursor to sulfuric acid. Contents 1 Structure and bonding 2 ... - read more
Best Answer: Three. Sulfur is the center; each structure has S double-bonded to a different O; the other two O's are single-bonded to S. (The reason is, if you count valence electrons, there are 24, but 32 are needed for octets, so #(bonds) = (32-24)/2 = 4 total). - read more
