  • Humic Functional Groups

    792 Words  | 4 Pages

    Humic substances are commonly described as heterogeneous compounds contain many functional groups and they can be viewed as polyfunctional ligands. Oxygen-containing functional groups are the most abundant and are ultimately the most important for binding metal ions (Logan et al., 1997). The presences of functional group in organic compounds that have unshared pairs of electrons, and that can form coordinate linkages with metal ions (Fig.3) are in the order of decreasing affinity of organic groupings

    So, we can say that butane and isobutane are structural isomers. !!!Types of Structural Isomers and Examples Now that we know what structural isomers mean, let’s discuss the different types of structural isomers. These are chain isomers, functional group isomers and positional isomers. !!Chain Isomers __Chain isomers__ are a type of structural isomers that differ in terms of the branches in their carbon chains. For chain isomers, we can imagine removing one carbon and its attachments in a

    to the impurities. For further conformation of the purity of experimental benzil, the infrared spectroscopy was observed. . The following functional groups were determined on the infrared spectroscopy according to their corresponding wavenumbers: aromatic, sp2 C-H bonds, and C=O/carbonyl group (Table 4). Benzil incorporates all of the above functional groups. The melting and infrared spectroscopy confirmed that the final product created was Benzil. In the following reaction, benzil was rearranged

  • Synthesis Of Methyl Cinnamate

    1992 Words  | 8 Pages

    Introduction The ester that was developed throughout the entire lab is known as methyl cinnamate. Methyl cinnamate is an ester that is created when cinnamic acid is mixed with methanol and sulfuric acid (see Scheme 1). Around the world, methyl cinnamate is found in a variety of plants and fruits such as strawberry or cinnamon. The plant most used to collect higher concentrations of methyl cinnamate is the Eucalyptus olida with a concentration of 98%. Due to the fact that the ester comes from a cinnamic

  • The Use Of Glycerol Residue

    Transform Infrared Spectrometry (FTIR) and Scanning Electron Microscope instruments. Based on the results, the functional group appearing for treated and commercial glycerol is the hydroxyl, aromatic methoxyl, alkenes, soap, carbonyl and alcohol group. The hydroxyl group which is O-H appeared at a spectra value of 3394.2700 cm-1for the treated glycerol and 3299.9600 cm-1 for the commercial group. Respectively. From the analysis of SEM for bead, it was found that majority of pores fall within range and

  • Benzocaine And 9-Fluorenone Lab Report

    molar hydrochloric acid was added, which immediately formed two layers, the top acidic aqueous layer was clear in color and contained benzocaine, and the bottom organic formed was yellow and contained benzoic acid and 9-fluorenone. Benzocaine’s amino group is protonated by the aqueous layer hydronium. This protonation forms the conjugate acid of benzocaine, benzocaine hydrochloride. Thus, the conjugate acid, benzocaine hydrochloride is a salt in which is soluble in water and furthermore can be isolated

    Ecstacy.MDA. Nutmeg. A ubiquitous spice that can be found in kitchens worldwide, nutmeg has been harnessed in cooking, rituals, and a multitude of different ways across multiple cultures for millennia (Baxamusa, 2011). Its most common use in near day-to-day cooking is something that is not given a lot of thought to, but with Drug culture becoming increasingly prevalent in younger demographics, nutmeg has become a cheap and easily sourced alternative (Shafer, 2010). Through analysis of its chemical

    is composed of compounds that have the same general formula (functioning group), usually the only differentiation is the length of the carbon chain or number of monomers. The difference in the length of the carbon chain can have an effect on many physical properties of the chemical, for example the boiling point. Alcohols are organic compounds in which one or more hydroxyl (-OH) groups is bound to a carbon atom. This group of compounds plays a key role in the world, ranging from alcoholic beverages

    (ethyl vanillin). This increase in polarity is due to the extra alcohol group in the ethyl vanillin alcohol and the smaller Rf value also indicates it is more polar and pure than the ethyl vanillin. 3. The IR spectrum of the starting material shows a medium/strong C-O bond at around 1500cm-1, also the starting material shows a strong C-H bond at around 3000cm-1 and another medium C-H bond at 2865cm-1 indicating an aldehyde group whereas the product does not. The IR spectrum of the product shows a

    organic layer, we had a melting point range of 240-243°C. For the IR spectra, we did note the C-Cl bond although there was not an OH bond present. ANALYSIS The reaction involves a nucleophilic acyl substitution on an aldehyde, with the leaving group concurrently attacking another aldehyde in the second step. First the Potassium hydroxide attacks a carbonyl, which forms a tetahedral intermediate which then collapses when attacked by another hydroxide. The carbonyl is formed again when its hydride
