3. Question
Select the incorrect statement.
The canonical forms have no real existence.
The molecule exist for a certain fraction of time in one canonical form and for other fraction of time in other canonical form.
There is no such equilibrium between the canonical forms as between tautomeric forms in tautomerism.
The molecule as such as a single structure which is the resonance hybrid of the canonical forms and which cannot as such be depicted by a single lewis structure.

Wrong Answer
4. Question
Select the incorrect condition for hybridisation:
The orbitals present in the valence shell of the atom are hybridisd.
The orbitals undergoing hybridisation should have almost equal energy.
Promotion of electron is an essential condition prior to hybridisation.
It is not necessary that only half filled orbitals participate in hybridisation. In some cases, even filled orbitals of valence shell take part in hybridisation.
