7. A:- resonance stabilizes the molecule R:- energy of resonance hybrid is less than the energy of any single Canonical structure

Q.

Assertion (A): Energy of resonance hybrid is equal to the average of energies of all canonical forms.

Reason (R): Resonance hybrid cannot be presented by a single structure.

Q. $\underset{–}{Statement-I:}$ The canonical forms have no real existence
$\underset{–}{Statement-II:}$ There is no equilibrium between canonical forms
$\underset{–}{Statement-III:}$ The energy of the resonance hybrid is less than the energy of any single canonical structure
$\underset{–}{Statement-IV:}$ The molecule does not exist for a certain fraction of time in one canonical form and for other fraction of time in other canonical form
Correct statements is / are

Q. Resonance energy will be more if Canonical structure are equivalent than if canonical structure and non- equivalent for the same species .Molecule is aromatic than le is not aromatic .

Q. Energy of the resonance hybrid of nitrobenzene is $E_{0}kJ/mol$ and nitrobenzene has the following resonating structures with their energies given below:

Resonating structure	Energy
	$E_1$
	$E_2$
	$E_3$
	$E_4$
	$E_5$

The correct representation of the resonance energy would be:
