Concept explainers
(a)
Interpretation: The given resonance structures are to be labeled as major, minor, or equal contributors to the hybrid and the hybrid is to be drawn.
Concept Introduction: Two resonance structures are different and the hybrid looks like the better resonance. Better resonance structure is the one which has major contribution in the hybrid and others are minor contributors. Major contributor is the resonance structure which possesses more bonds and fewer charges.
