Problem: Which of these molecules and polyatomic ions cannot be adequately described using a single Lewis structure?  Check all that apply.CO32-COH2HCNO3NH4+OF2

FREE Expert Solution

We have to determine which of the given polyatomic ions cannot be adequately described with a single Lewis structure.

This problem is based on Lewis structures and resonance forms. A Lewis structure shows the placement of atoms in a molecule and the distribution of electrons among atoms.

A resonance structure shows the delocalization of electrons in a molecule. Resonance structures differ only in the placement of electrons.

Molecules having multiple resonance forms cannot be described adequately with a single Lewis structure.
