For sulfur trioxide, SO3, decide which set of resonance structures contributes most to the resonance hybrid: (i) structures in which sulfur obeys the octet rule with one S=O double bond and two S–O single bonds, or (ii) structures in which sulfur forms three S=O double bonds. Justify your choice in one sentence using formal-charge considerations.
