Question
Chapter 4, Problem 4.100CP
Interpretation Introduction
Interpretation:
The resonance structures for PO43- should be drawn.
Concept introduction:
When more than one Lewis structure can be drawn for a molecule or ion, then it is said to have resonance.
It is generally the delocalization of electrons (bonds) over three or more atoms in a molecule for which one simple Lewis structure cannot depicts its correct structure.
