Concept introduction:
The change in reactant concentration over the course of the specified period can be viewed as the rate of a chemical reaction. According to the rate rule, the active concentration of the reactant molecules directly affects how quickly a chemical reaction proceeds. The rate constant is the name for the proportionality constant.

- Why is the mechanism shown in Figure 28 not plausible? * A- The reagent does not have a good leaving group. B- Water is too weak a base for the reaction to occur. C- The structure of the haloalkane prevents the nucleophile from coming close to the alpha carbon atom. D- None of these statements are correct. E- All these statements are correct.arrow_forward10 What is the rate of reaction when the transition state free energy is 22.84 kJ/mol? What is the rate of reaction when the transition state free energy is 142 kJ/mol? SHOW YOUR WORK.arrow_forwardDraw 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_forward
- Using fishhook arrows to propose an initiation step for the reaction. Light (hν) induces homolytic cleavage of a weak bond. The Sn-H bond is rather weak and is therefore highly susceptible to homolytic cleavage.arrow_forward1. b) Show the MECHANISM for the POLAR addition of molecular chlorine to cyclopentane. c) The reaction of toluene and ethylbenzene was through the alkyl groups, -CH 3 and -CH 2 CH 3, respectively. Why didn’t xylene, which has TWO methyl groups, react with bromine in the time allotted?arrow_forwardIf doubling the concentration of a reagent quadruples the reaction rate of that reagent, what should be the order of the reaction of this reagent? a) The order of the reaction is 0 b) The order of the reaction is 1 c) The order of the reaction is 2 d) The order of the reaction is 4arrow_forward
- For the competing reactions 2A-->R with rate constant k1 and 2A-->S with rate constant k2, the concentration of R is 3 M while that of S is 0.2 M when starting with 10 M of pure A after 1 hr. a) What is the selectivity if R is the desired product? (A) 50 (C) 1/15 (B) 10/3 (D) 15 b) What is the remaining amount of A? (A) 4 M (C) 36 M (B) 18 M (D) 7.2 Marrow_forwardIn the reaction observed in part III, where is the slow step? do you expect the reaction in part III to be faster for tert-butyl chloride or 2-chloropropane and why? Part III Silver Nitrate Test for Tertiary Alkyl Halides Set up the reaction. Obtain three 13 100 test tubes and label 13. Pipet 10 drops of distilled water into Test Tube 1. Pipet 10 drops of tert-butyl chloride into Test Tube 2 Pipet 10 drops of your product into Test Tube 3. Add approximately 1 mL of the 1% ethanolic silver nitrate solution to each test tube. Swirl each test tube to mix the contents. The appearance of a white precipitate indicates the presence of a 3° halide. Record your observations in the data table. Note: Avoid getting the AgNO3 solution on your skin. At the end of the experiment, discard the solutions as directed by your instructor.

The diagram is to illustrate your "reaction" progress of your experience as you navigated this week. Add as many transition states and intermediates that you see fit (be sure to give detail of each hill and valley). For example: What was the highest, lowest, moderate transition state during your reaction and why? Was your experience exothermic or endothermic? (draw accordingly (-))arrow_forward
