MCQ
What is not true about resonance? 
  • A
    The resonating structures are hypothetical
  • B
    The unpaired electrons in various resonating structures are same
  • ✓
    Hybrid structure is most energetic
  • D
    Hybrid structure Is least energetic
✓

Answer

Correct option: C.
Hybrid structure is most energetic
c
The Hybrid structure of the resonating structures is more stable than other structures because the energy of the resonance hybrid is less than other resonating structures. So its stability is high
