and Cristel Bernice T. Wee Group 10 2G-Medical Technology Organic Chemistry Laboratory ABSTRACT Hydroxyl group refers to a functional group containing OH- when it is a substituent in an organic compound. It is also known as the characteristic functional group of alcohols and phenols. On the other hand, carbonyl group refers to a divalent chemical unit consisting of a carbon and an oxygen atom connected by a double bond. It is known as the characteristic functional group of aldehydes
Borneol; An Oxidation-Reduction Scheme Nicolas Gibson Lab Time: Tuesday 11:30 am Abstract: In this experiment, the main objective was to synthesize a ketone from borneol via an oxidation reaction and secondly, to produce a secondary alcohol from camphor via a reduction reaction. Therefore, the hypothesis of this lab is that camphor will be produced in the oxidation reaction and isoborneol will be the product of the reduction reaction because of steric hindrance. For the oxidation
comvines two carbonyl compounds to form a new B-hydroxy carbonyl compound. These products are known as aldols, from the aldehyde + alcohol, a structural motif seen in many of the products. Aldol structural units are found in many important molecules, whether naturally occuring or synthetic. For example, the aldol reaction has been used in the large-scale production of the commodity chemical penaerythritol and the synthesis of the heart disease drug Lipitor. The aldol reaction unites two relatively
alcohols are oxidised to aldehydes, carboxylic acids and ketones depending on the starting material and type of reaction used. Systematic name is alkanals but aldehydes is used as it means alcohols dehydrogenated. Aldehydes have the functional group HC=O. Question stick to where in a molecule must an aldehyde be? Systematic name for ketones is alkanone. C=O is the functional group. Question stick for where in the molecule must the ketone be? Students practising naming do the first one as a class
Urinalysis is a test done on urine in order to diagnose a patient of a wide range of disorders, diseases, and conditions. There are several urinalysis test such as pH, ketones, specific gravity and glucose to name a few. There are three different exams that can be done to identify abnormalities; one of the exam is chemical exam. In a chemical examination a laboratorian uses a dipstick test that changes color in reaction to certain concentrations of a substance that could be in urine.
The purpose of this experiment was to identify one ketone with Thin Layer Chromatography and one using NMR spectrometry. We will do this by making 2, 4 a DNPH derivative and checking the melting points. Theory: By Using specific methods of compounds detection, we can match an unknown compound with a known compound because similar compounds will display similar characteristics. In this experiment, identifications of the unknown ketone was accomplished using thin layer chromatography, melting
Abstract In this study, the concept of cooperative cation binding catalysis was elegantly applied for direct generation of two contiguous tertiary and quaternary stereogenic centers. Using a highly accessible chiral oligoethylene glycol (oligoEG) as a cation-binding catalyst, asymmetric Mannich reaction of α-thiocyanato cyclic ketones as Mannich donors was performed with α-amido sulfones as the bench-stable imine precursors in the presence of potassium fluoride as the base, affording α-thiocyanato-β-amines
benzaldehyde, but purity was assumed and therefore melting point was not taken. Benzaldehyde is a simple aromatic compound with a aldehyde group; therefore, expected peaks are the aromatic ring constituents, C=O bond representative of aldehydes, and C-H bonds representative of aldehydes. According to the expected literature values in place for this functional groups, benzaldehyde was sufficiently pure, containing all the correct values. With the correct IR spectrograph available, all following IR samplings
CHAPTER TWO RESULTS AND DISCUSSION 2.1 Synthesis of 1,3-butadienes Dienes can be synthesised from aldehydes and ketones using the Wittig reaction. The Wittig reaction facilitates the synthesis of new carbon-carbon double bonds at specific locations in aldehydes and ketones (Bernard & Ford, 1983). The overall reaction mechanism is shown in Figure 1. Protocols for synthesising 1,3-butadienes from aldehydes and ketones have been established in the literature. The synthesis protocol proposed by
LAB 9: REDUCTION OF CARBONYL COMPOUNDS: PREPARATION OF FLUORENOL (Preparative) Introduction The first purpose of this lab was to reduce 9-Fluorenone to 9-Fluorenol using a selective metal hydride reducing agent- Sodium Borohydride (NaBH4) in Methanol solvent and acidification. The second purpose of this lab was to identify the 9-Fluorenol product via melting point and Infrared spectroscopy analysis and characterize the purity. The third purpose of this lab was to define the efficiency of lab technique
