- The rate law for the reaction of HO- with tert-butyl bromide to form an elimination product in 75% ethanol/25% water at 30 °C is the sum of the rate laws for the E2 and E1 reactions. What percentage of the reaction takes place by an E2 pathway when [HO-] = 5.0 M? (k2 = 7.1 * 10 - 5, and k1 = 1.5 * 10 - 5) rate = rate law for the E2 reaction + rate law for the E1 reation rate = k2 3tert@butyl bromide43HO-4 + k1 3tert@butyl bromide4arrow_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.

- Consider the reaction of 2-chloro-2-methylpentane with sodium iodide. Assuming no other changes, how would it affect the rate if one simultaneously doubled the concentration of 2-chloro-2-methylpentane and sodium iodide?arrow_forwardIn a reaction involving the iodination of acetone, the following reaction mixture was used: 5.00mL 4.0M acetone, 5.00mL 1.0 M HCl, 5.00mL 0.0050 M I2, and 10.0 mL water. what was the molarity of the acetone in the reaction mixture? (Recall that M1V1=M2V2) the color of the above reaction mixture disappeared in 250 seconds.

If a student accidentally adds 11 mL of 0.005 M iodine instead of 10 mL of 0.005 M iodine, how will their rate be effected?arrow_forwardAssignment 4 - Energy Diagram Illustrating Your Experience of Snowmaggedon The instructions are simple, draw an energy diagram (or reaction coordinate diagram) that illustrates your experience during our snowmaggedon (think Sn1/Sn2/E1/E2 reaction coordinate diagram). 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
- Joshua, an organic chemistry student, successfully performed a nucleophilic substitution reaction in the lab using2-bromo-2-methylpropane and methanol. The professor asked the student to repeat the experiment but increase the rateof the reaction by a factor of 4. How would the student achieve an increase in the rate of the reaction when performingthe experiment again?arrow_forwardUsing 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_forward10 What is the rate of reaction when the transition state free energy is 22.84 kJ/mol?
