Per NCERT §4.3.5 (misconceptions), which statement about RESONANCE is INCORRECT?
AThe actual molecule is the resonance hybrid
BResonance LOWERS the energy of the molecule (stabilisation)
CCanonical forms have no real existence
DThe molecule exists as an equilibrium that flips between canonical forms — flipping back and forth
Answer & Solution
Correct answer: D. The molecule exists as an equilibrium that flips between canonical forms — flipping back and forth
Per NCERT §4.3.5 misconceptions: there is NO flipping or equilibrium between canonical forms. The molecule HAS a single hybrid structure, more stable than any one canonical form.
