Introduction In a Grignard reaction‚ a Grignard reagent (R–MgX) adds to the carbonyl group in an aldehyde or ketone to form an alcohol (Figure 1). The reaction of a Grignard reagent with formaldehyde can be to synthesize a primary alcohol‚ with any other aldehyde can be used to synthesize a secondary alcohol‚ while the reaction with ketone is useful in the synthesis of a tertiary alcohol. Figure 1. General reaction mechanism of a Grignard Reaction The preparation of the Grignard reagent involves

The purpose of this experiment was to synthesize triphenylmethanol from a Grignard reagent. The Grignard reaction technique was used in this synthesis but due to the fact that it is such a strong nucleophile and base‚ it was important to prevent water from interfering with the Grignard reaction. Purity of the product was determined by measuring the melting point. Reagent Table: Structure Name Molecular formula Molar mass Density Melting point Boiling Point Diethyl ether C4H10O

Title: Studying SN1 and SN2 Reactions: Nucleophilic Substitutions at the saturated carbon Lab Partner: Jeszie Geronimo Objective and purpose: the purpose of this experiment is to convert a primary alcohol to an alkyl bromide using a Sn2 Reaction. Investigate some factors that influence the rate of Sn1 reactions. The second part of this lab will focus more on how unlike factors influence the rate of reactions in anSN1 reactions. The factors that we will be inspecting are the leaving groups‚ Cl-

Chemical Reactions Lab Report Introduction: Chemical reactions is a process that involves rearrangement of the molecular or ionic structure of a substance. There are different types of reaction such synthesis‚ decomposition‚ single replacement‚ double replacement‚ and combustion. Synthesis is where two or more reactants combine to create a product. For Decomposition‚ it is the opposite where a product breaks down into reactants. In Single Replacement‚ reactants switches an element with another element

Introduction – Lab Report What is a Chemical Reaction? A chemical reaction is a change in matter that produces one or more new substances. A chemical change or reaction occurs when bonds are broken and new ones are formed. The formation and dissolution of these bonds are dependent upon environment changes. Even without the usage of microscopes‚ chemical reactions are usually apparent to the naked eye. The two main kinds of changes that one can observe are the formation of new substances and changes

Chem 51LC Experiment 6 Lab Report Aldol Reaction Purpose: The purpose of this experiment is to be able to conduct an aldol condensation reaction using an unknown aldehyde and an unknown ketone. H NMR is used to identify the unknown aldehyde and ketone. Melting point is used to identify the aldol condensation reaction. Theory: Condensation reaction is also known as a dehydration reaction. In the mechanism of condensation reaction‚ a bond is formed between two molecules and creates water as a

The purpose of the lab was to find out the chemical elements based on the color of the flame that elements make by their reaction. The work we completed in the lab was testing the chemical effects of the flame from the chemicals. We tested different elements and wrote down our observations. I accomplished the knowledge of testing chemicals and making responses based on our observations.Electrons are the particles found in the chemicals that may be responsible for the production of colored light.

Lab report April 14‚ 2013 Abstract: In this article‚ we will experiment on the significant in strength of the enzyme by using three different test tubes and measuring the amount of product they give off. To determine this we are going to test the amount of color absorbance by using a special tool to help us understand our results. We will see how our end results show the effect of the amount of concentration we apply to each test tube. The results would be shown by the support of two graphs
