1. Based upon the results obtained in your experiment, formulate a mechanism that will account for all products observed. What rule does the mix follow? 2. One student refluxed the reaction mixture for 20 minutes instead of just distilling over the product as it is formed. The resultant product was approximately 100% 1-methylcyclohexene. Explain why this happened. 3. The GC depicted in Fig. 1 was obtained on analysis of the dehydration of the alcohol below. Interpret the GC data in...

A student studied the clock reaction described in this experiment. She set up Reaction Mixture 2 by mixing 20 mL 0.010 M KI, 10 mL .001 M Na2S2O3, 10 mL .040 M KBrO3, and 10 mL 0.10 M HCl using the procedure given. It took 45 seconds for the color to turn to blue. a. She found the concentration of each reactant in the reacting mixture by realizing that the number of moles of each reactant did not change when...

For an equilibrium reaction at a particular temperature, 2 A+B=20 a) One equilibrium mixture has the following concentrations: [A] = 0.30 M, [B] - 0.20 M, and [C] = 0.50 M. Calculate the value of K. b) Another reaction mixture has the following concentrations: [A] = 0.40 M, [B] = 0.40 M, [C] = 0.40 M. Is this mixture at equilibrium? If not which direction will the reaction move to reach equilibrium?

Procedure: Measure and dispense 0.6 ml of a 4.4 M otion of sodium methoxide in methanol and me of ethanol into a 5 mL reaction vial. Add 2.5 mmol of acetaminophen (40.378. Set up for reflux in the rume hood and bring reaction to reflux for 15 minutes (solvent is boiling and vapors are condensing condenser). After 15 minutes, directly through the top of the condenser tube, carefully add 0.3 ml of iemy iodide. Continue to reflux for another 45...

CONCEPT QUESTIONS (1) Instead of dropwise addition of anthranilic acid and isoamyl nitrite to the reaction vessel, a student adds all of their anthranilic acid and isoamyl nitrite in two portions. The remaining portion of the experiment is completed, and the student takes TH NMR and C NMR spectra of their final solid, as shown below. "H NMR Spectrum of Sample (300 MH2, DMSO, 25 °C) PPM 2M 1H1M INC NMR Spectrum of Sample (100 MHz, DMSO, 25°C) 2244 PPM...

Electrophilic bromination of an equimolar mixture of methylbenzene (toluene) and (trifluoromethyl)benzene with one equivalent of bromine gives exclusively 1-bromo-2-methylbenzene and 1-bromo-4-methylbenzene. Explain why none of the (trifluoromethyl)benzene reacts Explain the regiochemical outcome of the reaction In other words, why are 1-bromo-2-methylbenzene and 1-bromo-4-methylbenzene formed from the toluene? Electrophilic nitration of benzoic acid gives almost exclusively 1,3-nitrobenzoic acid. By drawing the appropriate resonance forms of the intermediate cations resulting from attack of [NO2]+, explain this result.
