Chapter 9, Problem 9.7YT

Interpretation Introduction

Interpretation:

All the resonance structures of the sulfonate anion ${\text{MsO}}^{-}$ are to be drawn.

Concept introduction:

Resonance structures are alternate valid Lewis structures that can be drawn for the given molecular or ionic formula. The resonance structures can be interconverted by rearrangement of lone pairs and/or $\text{π}$ electron pairs only. The movement of the electron pair is from an electron-rich site (atom or bond) toward an electron-poor site. The pair can move only to the adjacent atom or position. There is no change in the connectivity of the atoms. This movement of electrons results in delocalization of ionic charge on to more than one atom.
