- The following transformation can be accomplished by reactions we have studied in this chapter and Chapter 20. Name the type of reaction used in each step.arrow_forwardComplete the following reaction schemes. Some may take more than one step and some may have several routes to the product.arrow_forward2. Draw the structures and explain why CH3CH₂O and CH3CO₂ are good nucleophiles but CH3SO3, water, and alcohols (R-OH) are poor nucleophiles. Propose a 'cutoff' for the amount of negative charge needed to be a good nucleophile. CH3CH₂O CH3CO₂ CH3SO3 H₂O CH₂OHarrow_forward
- The reaction of an amine with an alkyl halide gives an ammonium salt. The rate of this SN2 reaction is sensitive to the polarity of the solvent. Draw an energy diagram for this reaction in a nonpolar solvent and another in a polar solvent. Consider the nature of the transition state, and explain why this reaction should be sensitive to the polarity of the solvent. Predict whether it will be faster or slower in a more polar solvent.arrow_forwardDrawing the Products of an SN1 Reaction Label the nucleophile and leaving group, and draw the products (including stereochemistry) of the following SN1 reaction.arrow_forwardAcyl transfer (nucleophilic substitution at carbonyl) reactions proceed in two stages via a "tetrahedral intermediate." Draw the tetrahedral intermediate as it is first formed in the following reaction. You do not have to consider stereochemistry. Include all valence lone pairs in your answer. Do not include counter-ions, e.g., Na+, I-, in your answer. In cases where there is more than one answer, just draw one.arrow_forward
- The SN2 reaction shows a reversible mechanism when the basic strength nucleophile and leaving group are similar, but not when the strength of the nucleophile as a base is greater than that of the leaving group. Explain.arrow_forwardIn the following SN2 reactions, identify the nucleophile and the electrophile. In addition, drawthe products of each reaction (including the inorganic byproducts).arrow_forwardAcyl transfer (nucleophilic substitution at carbonyl) reactions proceed in two stages via a "tetrahedral intermediate." Draw the tetrahedral intermediate as it is first formed in the following reaction. H3C NH₂ HCI/H₂O reflux • You do not have to consider stereochemistry. • Include all valence lone pairs in your answer. • Do not include counter-ions, e.g., Na+, I, in your answer. • In cases where there is more than one answer, just draw one.arrow_forward

Using the provided starting structure, draw the curved electron-pushing arrows for the following reaction or mechanistic step(s). Be sure to account for all bond-breaking and bond-making steps. Then draw the organic product of this reaction. Include all lone pairs in the structures. Ignore inorganic byproducts, counterions, and solvents.
