For the reaction below, draw the structure of the stabilized reaction intermediate in the box below. CI F3C CF3 NO₂ F3C N CF3 NO₂ • You do not have to consider stereochemistry. • Draw the Meisenheimer complex with a formal charge of 0 on the nucleophilic atom. If more than one resonance structure is possible, only draw the most important one.arrow_forward22. a. Label the reactive features, highlight the most reactive one, then highlight what it needs. Also, state if the reaction will start to create a carbocation, carbon radical, or carbanion, or will cause loss of aromatic character. If a carbocation, carbon radical, or carbanion starts to develop, label where that will occur. sec-butyl ethyl ether + HCl in water b. Use mechanism arrows to illustrate the reaction that occurs. c. If applicable, use stabilization resources to deal with the carbocation, carbon radical, or carbanion that starts to develop during the reaction, and draw the structure of any resonance-stabilized intermediate. d. Continue labeling and diagramming the reaction until you find the major stable product(s). e. Finally, state the stereochemistry of the major product(s) and use either Fisher projection or perspective formula representations to illustrate that stereochemistry.arrow_forward
- Give the products of the following substitution reactions. For every reaction, show electron pairs on both nucleophile and leaving group.arrow_forwardThe SN1 mechanism starts with the rate-determining step which is the dissociation of the alkyl halide into a carbocation and a halide ion. The next step is the rapid reaction of the carbocation intermediate with the nucleophile; this step completes the nucleophilic substitution stage. The step that follows the nucleophilic substitution is a fast acid-base reaction. The nucleophile now acts as a base to remove the proton from the oxonium ion from the previous step, to give the observed product. Draw a curved arrow mechanism for the reaction, adding steps as necessary. Be sure to include all nonzero formal charges.arrow_forward1. Predict the product, and propose a mechanism for the following nucleophilic addition to aldehyde or ketone. Are the products different from one another?
