(a)
Interpretation:
The energy diagram of the reaction for Problem 20.28(a) is to be drawn.
Concept introduction:
The energy diagram of a reaction shows the changes in relative energies of the species involved in the reaction as the reaction progresses from the reactants to the products.
The relative energies depend mostly on charges and resonance stabilization.
Charged species are generally less stable, i.e., higher in energy than uncharged species.
Species in which charges are delocalized by resonance are lower in energy than species without resonance delocalization.
(b)
Interpretation:
The energy diagram of the reaction for Problem 20.28(b) is to be drawn.
Concept introduction:
The energy diagram of a reaction shows the changes in the relative energies of the species involved in the reaction as the reaction progresses from the reactants to the products.
The relative energies depend mostly on charges and resonance stabilization.
Charged species are generally less stable, i.e., higher in energy than uncharged species.
Species in which charges are delocalized by resonance are lower in energy than species without resonance delocalization.
(c)
Interpretation:
The energy diagram of the reaction for Problem 20.28(c) is to be drawn.
Concept introduction:
The energy diagram of a reaction shows the changes in the relative energies of the species involved in the reaction as the reaction progresses from the reactants to the products.
