Resonance in molecules:
ADoesn't exist
BMeans actual structure is one of the resonance structures
CMeans the actual structure is a HYBRID of contributing resonance structures, with delocalized electrons
DIs only for inorganic compounds
Answer & Solution
Correct answer: C. Means the actual structure is a HYBRID of contributing resonance structures, with delocalized electrons
Resonance structures are not interconverting; the real molecule is a hybrid — its electrons are DELOCALIZED. Example: benzene's six C-C bonds are all identical 1.5-order, not alternating single-double.
