Which of these molecules and polyatomic ions cannot be adequately described using a single Lewis structure? Check all that apply.
CO32-
COH2
HCN
O3
NH4+
OF2
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.
