Concept introduction:
Energy diagrams are used to depict graphically the energy changes that occur during a reaction. The vertical axis of the diagram represents the energy of all the reactants and the horizontal axis, called reaction coordinate, represents the progress of the reaction from beginning to end. The reactants are shown in left and the products in the right. The transition state represents the highest energy structure involved in the particular step reaction. The overall ΔG# is the energy difference between the reactants and highest transition state and overall ΔG0 is the free energy difference between the reactants and products. Every step in a reaction has a separate energy diagram.
To draw:
An energy diagram for a two-step reaction with Keq > 1. In the diagram the overall ΔG0, transition states, and intermediate are to be labeled. Whether the reaction has a positive or negative ΔG0 is also to be stated.

- For each reaction in question 20, sketch a reaction coordinate energy diagram indicating the starting materials, transition states and any intermediates, if present, in the reaction. Don't worry about the absolute energy of starting materials and products but you can assume that the product is more stable than the starting materials.arrow_forward7.

Nucleophilic attack leads to intermediate 2, which goes on to form the final product. In cases that involve a negatively charged nucleophile, the attack of the nucleophile leads directly to the product. H.
