| Reactions of Grignard Reagents with Carbonyls | | | Tuesday 1:30 | 2/28/2012 | | Introduction This experiment explores the reactivity pattern for the addition of Grignard reagents to three different carbonyl groups: a ketone‚ an ester‚ and a carbonate. Grignard reagents are organometallic compounds that have a carbon-metal bond‚ such as carbon-magnesium. Grignard reagents are formed from the reaction of an alkyl‚ cycloalkyl‚ or aryl halide and magnesium metal in dry ether

What Factors Affect Chemical Equilibrium? Introduction: In investigation 14‚ “What Factors Affect Chemical Equilibrium?”‚ the purpose was to find out which reagents caused a change in the chemical equilibrium. A deep red color was formed when Iron Nitrate [Fe(NO3)3 (aq)] was mixed with water and Ammonium Thiocyanate [NH4NCS (aq)]. The product of these two reactants was Iron Thiocyanate(FeNCS). After different trials of mixing the given reagents

Determining the Stoichiometry of Chemical Reactions Objective In this lab we took Fe(NO3)3 and NaOH and mixed 7 different mole ratios in graduated cylinders to determine what the mole ratio is. We also did the same thing with solutions of CuCl2 and Na3PO4. We determine the mole ratios by graphing the volume of reactant #1 vs. volume of precipitate for each reaction. Data Part 1.)

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

Objective: The purpose of this experiment was to prepare the Grignard reagent methylmagnesium iodide and react it with benzoin to form the 3o alcohol 1‚2-diphenyl-1‚2-propanediol‚ through an addition reaction pathway. Introduction: Grignard reagents are alkyl or aryl-magnesium halides that act as the nucleophile in Grignard reactions‚ where ketones are reacted with the reagent‚ then treated with acid to produce an alcohol. In the case of this experiment‚ methylmagnesium iodide was created

Purpose: To observe the reactions of specific aqueous solutions with specific aqueous reagents. Introduction: A solution is as a homogeneous mixture containing two or more substances. Reagents are added to solutions to create a chemical reaction or added to see if anything occurs. Reagents can be added to solutions to see if there is a presence of other substances. For example‚ iodine added to a lead solution. Iodine would be the reagent and would cause a chemical reaction confirming the presence

Organic compound From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search Methane is one of the simplest organic compoundsAn organic compound is any member of a large class of chemical compounds whose molecules contain carbon. For historical reasons discussed below‚ a few types of carbon-containing compounds such as carbonates‚ simple oxides of carbon and cyanides‚ as well as the allotropes of carbon such as diamond and graphite‚ are considered inorganic. The distinction between "organic"

Purpose This experiment deals with separating substances. The objective was to become familiar with the methods of separating substances from one another using decantation‚ extraction‚ sublimation techniques. Brief Introduction This experiment was set to teach research students different methods of separating substances from one another. Materials that are not uniform in composition are set to be impure or heterogeneous and are called mixtures. The separation of the components of mixtures is
