Benzene exists as a resonance hybrid and its bonds exhibit characteristics that are halfway between single and double bonds. Resonance hybrids are best defined as

Question

A. The average of two different structural isomers.

B. Special Geometric Isomers.

C. The average of two different arrangements of single and double bonds.

D. The average of two different geometric isomers.

Answer 1

None of these represent a perfect definition of resonance hybrids, but since the question deals specificallly sith benzene, the best answer would be

C. The average of two different arrangements of single and double bonds. The other "definitions" all use the term isomers, and resonance structures of a molecule are NOT isomers, but rather hypothetical structures representing delocalization of electrons.
