Can you imagine there are certain things we come across in our daily life that contain carboxylic acids? For instance, do you know human vomit and body odor contains members of the carboxylic acid group? Human vomit contains butyric acid whereas body odor contains propionic acid. The properties of carboxylic acids depend upon the structure and presence of carboxyl group. Similarly, formic

  • Asymmetric Porphyrin Synthesis

    859 Words  | 4 Pages

    The methodology involved a condensation reaction between an aldehyde and pyrrole to form porphyrinogen, followed by the oxidation step sequentially. This method also allows for milder conditions, while various types of functional groups and protecting groups such as alkyl groups, alcohol, dioxane, can be introduced into the porphyrin meso position. Lindsey’s method can be considered as the easiest method to produce meso-subtituted porphyrins with yields up to 50% can be achieved depending on the

    DERIVATIVES Carboxylic acids One of the derivatives of the carboxylic acid is the organic compound with a functional group of –COOH. Carboxylic acids are also can be divided into two main compounds; ie aromatic and aliphatic carboxylic acid. As such, we may refer to a chemical compound with two –COOH functional group as dicarboxylic acid.

  • Esterification Of Carboxylic Acid

    716 Words  | 3 Pages

    Esters are derived from carboxylic acids. A carboxylic acid contains the -COOH group, and in an ester the hydrogen in this group is replaced by a hydrocarbon group of some kind. This could be an alkyl group like methyl or ethyl, or one containing a benzene ring like phenyl. Carboxylic acid esters, formula RCOOR′ (R and R′ are any organic combining groups), are commonly prepared by reaction of carboxylic acids and alcohols in the presence of hydrochloric acid or sulfuric acid, a process called esterification

  • Aldol Condensation Lab Report

    1825 Words  | 8 Pages

    Aldol condensation In the aldol condensation the α-carbon of one aldehyde or ketone molecule adds to the carbonyl carbon of another. The base is most often used is -OH. The product is a β-hydroxy aldehyde or ketone, which in some cases is dehydrated during the course of the reaction. Even if the dehydration is not spontaneous, it can usually be done easily, since the new double bond will be in conjugation with the C=O bond.   Ritter Reaction Alcohols is converted by a strong acid to a carbocation

    attached to an oxygen (O) atom by a hydroxyl group (-oh) and to a double bond by a sigma bond. A fourth bond links the carbon atom to a(H) hydrogen atom or to some anthor combining group. The (COOH) carboxyl group is so-named because of the (C=O) carbonyl group and (OH) hydroxyl group. Acidity is The main chemical characteristic of the carboxylic acids. They are generally have higher acidicty than other organic compounds containing (_OH) hydroxyl groups but are generally weaker than the familiar

  • Carbonyl Compounds Lab Report

    Introduction: We have seen that the carbonyl group of aldehydes and ketones is highly immediate, and that accompaniments to this functionality are ordinary. Carbonyl functionality reactive but that it also activates to hand carbon-hydrogen bonds (particularly alpha hydrogen’s) to go through a variety of substitution reactions.1 Carbonyl compounds can be explained by just four fundamental reaction types:  Nucleophilic additions  Nucleophilic acyl substitutions  α-Substitutions

  • Principle Of Grignard Reagent

    1057 Words  | 5 Pages

    Introduction Grignard reagent is considered as an organometallic compound or it's the composition of electrophilic and nucleophilic that electrophilic is the carbon atom of organic halide which is directly attached to the halogen, it's reactivity can be switched to the nucleophilic reactivity by conversion an organomagnesium halide. It has the general formula of (RMgX) and it has a general nomenclature which it's called magnesium alkyl halide. We can get Grignard reagent by adding one of solutions

  • Dimethyl Maleate And Carvone Lab Report

    969 Words  | 4 Pages

    For this experiment, stereochemistry was observed by analyzing both the isomerization of dimethyl maleate and carvones. The dimethyl maleate is formed by two methyl ester groups that are connected by an alkene. They are in a cis-conformation meaning they are on the same side of the alkene, therefore the esters are close to one another. This conformation is strained and sterically hindered due to electrons repelling each other and are enantiomers of one another. With the use of radical chemistry,
