- Draw an energy diagram for the SN2 reaction on the previous page. Your reaction coordinate diagram should: Include structures of starting materials, products, and transition states at correct relative energies. Indicate the activation energy of the rate determining step and whether the reaction is endothermic or exothermic. What makes this reaction endothermic or exothermic?arrow_forwardWhat are the organic products of these reactions? Are they electrophiles or nucleophiles? What is their decreasing order of rate?arrow_forwardOrder the compounds from most to least reactive in SN2 reactions. Explain why.arrow_forward
- Fill in the missing reagents in the boxes below. some steps may require more than one step.arrow_forwardFor which reaction mechanisms—SN1, SN2, E1, or E2—are each of the following statements true? A statement may be true for one or more mechanisms. a.The mechanism involves carbocation intermediates. b.The mechanism has two steps. c.The reaction rate increases with better leaving groups. d.The reaction rate increases when the solvent is changed from CH3OH to (CH3)2SO. e.The reaction rate depends on the concentration of only the alkyl halide. f.The mechanism is concerted. g.The reaction of CH3CH2Br with NaOH occurs by this mechanism. h.Racemization at a stereogenic center occurs. i.Tertiary (3°) alkyl halides react faster than 2° or 1° alkyl halides. j.The reaction follows a second-order rate equation.arrow_forwardAre the following nucleophiles, electrophiles, they be both a nucleophile or electrophile, or neither? pyridine alkenes Hg+ (ex. Hg(OAc)2 CH3ONa PBr3arrow_forward
- True or false 1.an intermediate is produced in the SN2 reactiom is a carboncation. 2.In SN1 reactions nucleophile HI will react faster than HCL 3.Halogenated waste can be disposed off in a general waste solvent.arrow_forwardWhy are SN1 reactions favored by polar protic solvents? Group of answer choices Polar protic solvents stabilize reaction intermediates Polar protic solvents cannot form hydrogen bonds. Polar protic solvents contribute leaving groups. Polar protic solvents contribute leaving groups.arrow_forwardHow do I perform this nucleophilic substitution reaction? Does this reaction have SN1 and SN2 occurring simultaneously?
