Answer:
(B) Resonance will be a stabilizing factor.
(D) Charge is delocalized over several atoms.
Step-by-step explanation:
Hello!
Resonance theory attempts to explain certain experimental data observed. Molecules such as benzene cannot be explained by previous theories because the experimental data does not match, for example, the link length is intermediate between a single and a double bond in said molecule.
Resonance theory explains the additional stability of certain molecules from the delocalization of electrons between several atoms.
