Draw a reaction-energy diagram (energy in kJ/mol) for the last step of a free radical substitution mechanism. Label correctly the: - axis (with units of measures, if applicable); - energy levels of reactants, products, transition states and intermediates (if applicable); - activation energy (or energies, if applicable); - heat of reaction (including its sign).

Draw a labelled reaction coordinate diagram for the both SN reactions. Label the activation energy (free energy of activation) and give the approximate structures of the intimal state, the transition states, the intermediate and product at the correct points along the reaction coordinate. Also, can you decide on the basis of the kinetic expression whether the t-butyl chloride-hydroxide ion reaction proceeds by a one-step or a two-step mechanism? Explain why observed kinetic expression is consistent with the mechanism you chose.
**WRITTEN WORK** Draw a detailed free energy diagram for the following Snl reaction. Include and label the overall reactants, the overall products, the intermediate(s), the axis, and the transition state(s). Br C1 Syl HTML Editore n = = X Х D
2. Draw an energy diagram for the first reaction in problem #1. Label the axis, reactants, products, any intermediates (if needed) and transition states. Than indicate using dotted a line how the diagram would change if CH,CH2OH was used as the solvent instead of acetone. 3. Draw the mechanism showing how the following molecule can best be produced using a SN2 reaction (the molecule shown below is the product, you need to determine the proper reactants (RX and Nu)).

4. Consider the reaction energy diagram below. Consider the "potential energy" to be equal to enthalpy. Potential energy Reaction progress First, indicate on the diagram the activation energy, transition state, and the change of enthalpy for every step of this step-wise process, as well as the change in enthalpy for the overall reaction. Then, answer the following questions: (i) How many elementary steps are there in the mechanism of this reaction? (ii) Which of these steps is the rate-determining step?...
The reaction below proceeds through an exothermic E2 mechanism. Draw the reaction coordinate diagram for this reaction, and label all activation energies, delta Gs, and transition states.
