Colin Burlison 1/9/13 AP European History Thermidorian Reaction DBQ In the time of the National Convention‚ (a governmental body existent for three years of the French Revolution) the government desired for total change from the Old Regime. The final change stemming from this desire was the introduction of the French Republican Calendar. In 1789‚ the Cahier de doléances (report of grievances)‚ from the Third Estate of Château-Thierry‚ said that they asked for the number of religious

Title Experiment 17 Reaction Kinetics- Determination of the Activation Energy of the Reaction Between Oxalic Acid and Potassium Permanganate. Objective To determine the activation energy of the reaction between oxalic acid and potassium permanganate. Theory and Background Activation energy is the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport. In terms of the transition-state

goal was to observe and note the reaction of butanols with hydrobromic acid. Before the lab began we discussed and proposed mechanisms. (see “Mechanisms”) To begin this experiment we calculated how much of each material we were going to be using‚ and the numbers we chose to use differed from our reference text slightly. We used 6.5 mL of our assigned butanol and only 4 mL of sulfuric acid. Going back to our reaction mechanisms‚ we were looking at SN1 and SN2 reactions‚ so we of course used the hydrobromic

Alkyl Halides Introduction Nucleophilic substitution of alkyl halides can proceed by two different mechanisms – the SN2 and the SN1. The purpose of the experiment was to identify the effects that the alkyl group and the halide-leaving group have on the rates of SN1 reactions‚ and the effect that the solvent has on the rates of SN1 and SN2 reactions. The SN1 mechanism is a two-step nucleophilic substitution‚ or unimolecular displacement. In the first step of the mechanism‚ the carbon-halogen

hydrochloric acid. The reaction occurs via nucleophilic substitution‚ in which a nucleophile replaces the leaving group in the substrate. In this case‚ the hydroxyl group of t-butyl alcohol is replaced by a chlorine atom. The reaction proceeds via Sn1mechanism. The second part of the experiment consisted of purification of t-butyl chloride using the distillation process. A nucleophile is any neutral or uncharged molecule with an unshared pair of electrons. In the substitution reaction‚ the nucleophile

Title: Prep of t-Butyl Chloride via SN1 Reaction Purpose: The purpose of this experiment is to synthesize tert-butyl chloride via an SN1 reaction. t-Butyl Chloride was synthesized from t-Butyl Alcohol using hydrochloric acid in separatory funnel; isolation of t-Butyl Chloride was done under distillation conditions. The experiment resulted in 8.29grams of purified compound‚ which is a 66.27 percent yield. Procedure: As per handout with changes Equation: Mechanism: Results: (Scan

Lab Report: Nucleophilic substitution reaction Introduction: Alkyl halides undergo many reactions in which a nucleophile displaces the halogen atom bonded to the central carbon of the molecule. The displaced halogen atom becomes a halide ion. | | | | Some typical nucleophiles are the hydroxy group (−OH)‚ the alkoxy group (RO−)‚ and the cyanide ion (−C N). Reaction of these nucleophiles with an alkyl halide (R—X) gives the following reactions and products: | | | |

Aim During this experiment I will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction. Preliminary work Before doing our main experiment‚ we will have to conduct another experiment‚ to see what concentration of acid we will have to use. We done this using 0.1M‚ 0.5M and 1M of Hydrochloric acid‚ and 0.1g of powdered limestone‚ we used powdered limestone‚ as it would be a fairer test‚ I think this as all the particles of limestone will
