Resonance Lewis Structure: Solutions

Brief about Solutions

This page gives an opportunities to see answers and to assess learners if they grasped the right knowledge on Resonance Lewis Structure.
It also helps learners to ensure their learning on aspects of Chemistry in general
The learner is supposed to draw structures and compare the S−O bond length in SO3.
It is strongly recommended to do the Exercise before looking at the provided answers (Part 3).

Question:

SO3 has three resonance Lewis structures.
Draw these structures and compare the S−O bond length in SO3 to a normal S−O single and S=O double bond lengths.

Solution:

so3-reasoance

Because of resonance, the S−O bond in SO3 is neither single nor double bond.
It is shorter than S−O single bond, but longer than S=O double bond.
