Question

which representation demonstrates a key limitation of lewis structures? choose one:

Explanation:

Lewis structures do not represent the three - dimensional geometry accurately. The third structure (the one with double - bonded oxygen and single - bonded oxygens) shows resonance, which is a key limitation as Lewis structures cannot fully represent the delocalization of electrons in resonance hybrids. In reality, the electrons in the resonance - stabilized species are spread out over the molecule, but Lewis structures depict them as localized in specific bonds.

Answer:

The third structure (the one with double - bonded oxygen and single - bonded oxygens)
