Question

The resonance energy is defined as a difference in energy between

• A. Two consecutive resonating structures
• B. Resonance hybrid and most unstable resonating structure
• C. Resonance hybrid and most stable resonating structure
• D. First and last resonating structures

Answer 1

The correct option is C Resonance hybrid and most stable resonating structure

The resonance energy is defined as a difference in energy between resonance hybrid and most stable resonating structure. The resonance energy of a compound is a measure of the extra stability of the conjugated system compared to the corresponding number of isolated double bonds.
