Diels-Alder reaction was performed in this experiment. Which is a reaction that was discovered by Otto Diels and Kurt Alder. This particular type of reaction is the concerted cycloaddition among a dienophile and a diene. The Diels-Alder reaction allows for the synthesis of stereospecific rings in an efficient manner. This reaction proceed in a single step method‚ otherwise known as Nucleophilic Substitution in the second order (SN2). The Diels-Alder reaction is categorized as a pericyclic reaction‚ this

Demonstration of the Rates of Reaction Between Sulphuric Acid (25mL ±0.5mL) and Magnesium (0.02g ±0.01g) Changing Due to Different Surface Areas By Chania Baldwin Introduction: When sulphuric acid and magnesium are added together‚ magnesium sulphate and hydrogen gas is created. To create such a reaction the atoms must collide with a sufficient amount of energy. Every reaction requires a different amount of energy to create the reaction‚ which is called the activation energy; when there is not enough

Link reaction The link reaction takes place in the mitochondrial matrix and its main function is to turn the pyruvate into acetate for the kerb cycle. During the link reaction the pyruvate molecule undergoes decarboxylation and dehydrogenation‚ the enzymes pyruvate decarboxylase and pyruvate dehydrogenase remove the carboxyl group (which becomes a carbon dioxide molecule) and removes the hydrogen atoms from the pyruvate molecule. The coenzyme NAD accepts the two hydrogen atoms and becomes reduced

CHEM111AC‚ Experiment#9 - Ionic Reactions Discussion/Error Analysis In the first part of this experiment‚ the student was presented with 7 unique and unidentified bottles of solutions labeled A-G and was expected to be able to analyze the 7 solutions through trial and error and mixing them with one another. For solution A: mixing A + B formed a precipitate‚ A + C generated heat‚ A + D gave no reaction‚ A + E gave no reaction‚ A + F gave no reaction‚ A + G formed a precipitate. For solution B: mixing

Purpose: To determine the effect of various factors on the rate of reaction between an enzyme andits substrate‚ and also to determine the optimal ranges under which the enzyme activity ismaximized. Also to determine whether saline and alcohol are inhibitors or activators Hypothesis: PH factor prediction: I predict that as the pH increases so the activity of the enzyme willincrease until it reaches optimum pH range (pH 7) because the enzyme is less denaturedwhen it reaches the preferred pH level

The Grignard Reaction Abstract Through the use of the Grignard reaction‚ a carbon-carbon bond was formed‚ thereby resulting in the formation of triphenylmethanol from phenyl magnesium bromide and benzophenone. A recrystallization was performed to purify the Grignard product by dissolving the product in methanol. From here‚ a melting point range of 147.0 °C to 150.8 °C was obtained. The purified product yielded an IR spectrum with major peaks of 3471.82 cm-1‚ 3060.90 cm-1‚ 1597.38 cm-1‚ and 1489

Grignard Reaction: Synthesis of Triphenylmethanol Hai Liu TA: Ara Austin Mondays: 11:30-2:20 Abstract: In this experiment‚ phenylmagnesium bromide‚ a Grignard reagent was synthesized from bromobenzene and magnesium strips in a diethyl ether solvent. The Grignard reagent was then converted to triphenylmethanol‚ a tertiary alcohol with HCl. The reaction for phenylmagnesium bromide was: The reaction for Grignard to triphenylmethanol was: In the formation of the Grignard reagent

In this laboratory voltmeters where utilized to take reading of three different electrochemical reactions: Pb/Zn‚ Pb/Cu‚ and Zn/Cu. A salt bridge was placed between two reactions containing metal strips in separate aq solutions. The salt bridge was placed in order to balance the reaction. The voltage measurements for Pb/Zn‚ Pb/Cu‚ and Zn/Cu where .595 V‚ .479 V‚ and 1.072 V accordingly. The values obtained where then used to determine the voltage value for the reduction half. The resulting cell potential
