Experiment 4: Kinetics of Nucleophilic Substitutions 1. Determine the effect of varying [OH-] on the rate of the reaction. To do this, you should complete the following table: Experiment [tBuCl]0 (M) [OH-]0 (M) Time (s) Reaction rate (M/s) Rate constant (s-1) 1 0.03 0.003 65 4.89 · 10-5 1.62 · 10-3 2 0.03 0.006 213 3.15 · 10-5 1.05 · 10-3 3 0.03 0.009 362 2.96 · 10-5 9.85 · 10-4 What is the dependence of [OH-] on the rate law? The effect of the increased or…

transferred to centrifuge tube and centrifuged at 4000 rpm for 10 min. The supernatant was filtered through Whatman filter paper No. 42. The filtrate was evaporated to dryness at 50oC using a vacuum evaporator. The residue was then redissolved in 5 mL acetone and vortexes to get homogenous samples. The lipophilic…

According to cerakoteguncoatings.com (2017), Cerakote is a Polymer-Ceramic coating that can be applied to metals, plastics, polymers and wood. Cerakote is used on; knives, weapons, tools, some electronic covers, glasses and anything durable that needs a tough coating. This ceramic thin-film coating is intended to offer an appealing finish with unequaled performance. The ceramic coating of Cerakote provides the advantage of having extraordinary; adhesiveness, pliability, corrosion and wear…

The estimated amount of time it took for the reactions that involved 2- chlorobutane, 2 – bromobutane, or 2 – chloro – 2 – methylpropane and 2 - bromobutane to form a precipitate could not be determined because no precipitate was formed. It makes sense that no precipitate was from because there was a lot of steric hindrance. The estimated amount of time it took for the reaction that involved 1 – chlorobutane could not be determined because at first glance it looked as if no precipitate formed.…

concentration, there would be a curve. The absence of a curve shows that the reaction occurs at a steady rate. A zero order reaction such as this typically occurs when other reactants have much higher concentrations, which is the case in this reaction. Acetone has a concentration of 4M, while HCl has a concentration of 1M. Additionally, iodine had such a low concentration because it is the rate determining reactant. Since the other two reactants were…

The DEA imposed choke points with chemical importation limits on two key chemicals for purification: acetone and magnesium permanganate or it's substitue sodium permanganate. The kerosene or gas used to dissolve the leaves would normally be washed out with these two chemicals. The best non pharma process today is lucky to achieve 92% purity. DNM that advertise…

Abstract A Friedal-Craft reaction was performed to synthesize 1,4-di-t-butyl-2,5-dimethoxy-benzene from p-dimethoxybenzene and t-butyl alcohol. The product of the reaction was filtered using a Hirsch funnel, before recrystallizing and filtering a second time. The recorded mass of the product was .08g and the melting point was 47-52.7 °C. Introduction1 This experiment was designed to practice working with electrophilic aromatic substitution reactions. Specifically, a Friedel-Craft reaction was…

Diabetes and Ketoacidosis According to the American Diabetes Association, the incidence of diabetes in Americans is nearly 1.7 million people per year. (American Diabetes Association, 2015). Diabetes is a condition that results in higher than normal blood-glucose levels, known as hyperglycemia. There are two forms of diabetes called Type 1 and Type 2. Type 1 diabetes, also known as insulin-dependent diabetes, is the result of the body’s inability to produce insulin. This is typically…

Although they may be oddly shaped, volumetric and Erlenmeyer flasks are closed-end air columns, and they abide by the conventional rules of resonance. When a rubber stopper is inserted into a flask some air is forced out of the flask, and the stopper seals the flask so the air cannot get back in. This creates an area of low pressure within the flask. When the stopper is quickly pulled out of the flask, the air rushes back into the flask because the pressure of the atmosphere is higher than the…

Aprons and goggles on. Clean a 1000-mL beaker for use as a heating bath. Set the beaker on a hot plate and begin heating. 2. Clean and completely dry the Erlenmeyer flask. 3. Cut a square of aluminum foil to serve as the cover of the flask. Trim the edges so that it neatly covers the edge of the flask. 4. Weigh the empty flask with cover and record to as many sigfigs as possible. 5. Obtain your unknown liquid and record the ID #. Add 3-4 mL of the liquid to the flask. Re-cover…
