Concept explainers
Interpretation:
The greatest resonance contributor from the given resonance structures is to be identified.
Concept introduction:
The lowest energy (more stable) resonance structure is the greatest resonance contributor to the hybrid. The stability of a resonance structure is governed by the following factors: greater number of atoms with octets, greater number of covalent bonds, and least number of formal charges. Further, the negative charge on the more electronegative atom and the positive charge on the least electronegative atom increase the stability of the resonance structure. The electron donating groups stabilize the positively charged atom, and the electron withdrawing groups stabilize the negatively charged atoms.

- Which of the these statements is correct? O All of these statements are correct. O The greater the predicted stability of a resonance contributor, the more it contributes to the resonance hybrid. O A resonance hybrid is more stable than the predicted stability of any of its resonance contributors. O The greater the number of relatively stable resonance contributors, the greater the resonance energy.arrow_forwardThe calicene molecule has a different dipolar moment of 0 and also thedipole points to the larger ring.
