  • Organometallic Reactions : Identification Of An Unknown Bromide

    1317 Words  | 6 Pages

    LAB 7: ORGANOMETALLIC REACTIONS: IDENTIFICATION OF AN UNKNOWN BROMIDE (Preparative) Introduction The first purpose of the lab was to prepare an unknown organomagnesium bromide, an organometallic reagent, reacting an unknown aryl bromide with magnesium in anhydrous ether. The unknown was chosen from a predetermined list of benzoic acid derivatives with varying molecular weights and melting points (see Supplement C). The second purpose of this lab was to prepare an unknown carboxylic acid by reacting

    and calculating the molecular weight obtained from titration. Organometallic compounds are compounds that contain carbon-metal bonds (C-M bonds), in which carbon bears a partial negative charge because metal is less electronegative than the carbon. This partial negative charge of the carbon atom allows it to be a good nucleophile that attacks the electrophile to make a new carbon-carbon bond. There are several examples of organometallic compounds, such as organolithium, Gilman reagents, and Grignard

    A Grignard-Like Organic Reaction The Synthesis of 1-phenyl-3-buten-1-ol Introduction The Grignard reaction is an important synthetic process by which a new carbon to carbon bond is formed. Magnesium metal is first reacted with an organic halide forming the Grignard reagent. The Grignard reaction is the addition of an organomagnesium halide (Grignard reagent) to a ketone or aldehyde, to form a tertiary or secondary alcohol, respectively. For example, the reaction with formaldehyde leads to

    quotation because it express what, I think, is the essence of teaching and learning. As a student, I have observed that the best teachers were those who cared the most about teaching. It is noteworthy to mention that, I loved the way of my organic chemistry teacher taught conformational

  • What Is Ferrocene?

    284 Words  | 2 Pages

    Ferrocene is an organometallic iron compound with a pentagonal anti-prismatic "sandwich" structure. Due to its high-symmetry sandwich structure, ferrocene has a number of interesting chemical and physical properties. This compound is widely used in chemistry, biology and pharmacology, both in industry and in scientific research. For ferrocenes, three main types of transformations are characteristic: the replacement of five-membered ring hydrogens, the oxidation at the iron atom, and the breaking

    and published a second paper on the subject. A better definition would be pH=-log[aH1+ ], where aH1+ denotes the activity of the H1+ ion. The activity of an ion is a function of many variables of which concentration is one. It is unfortunate that chemistry texts use a definition for pH that has been obsolete for over 50 years. Because of the difficulty in accurately measuring

  • Experiment 36: Determination of the Structure of a Natural Product in Anise Oil

    1269 Words  | 6 Pages

    Name CHE 173 Sec # January 25, 2005 Experiment 36: Determination of the Structure of a Natural Product in Anise Oil Purpose: The purpose of this experiment is to isolate the major component of anise oil and determine its identity and structure using melting point determination and IR spectroscopy. Introduction: The major component of anise oil has the chemical formula C10H12O. This compound is said to be hydrogen deficient, meaning that it contains less hydrogen atoms than would be needed for
