Carboxylic Acid Research Paper
Large numbers of carboxylic acids are found in nature. Carboxylic acids have very strong odors, especially the volatile derivatives of carboxylic acids. The properties of carboxylic acids depend upon the structure and presence of carboxyl group. The most commonly used carboxylic acid is the acetic acid which is found in vinegar. 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 acid is found in insect

However, a carboxyl group is formed by the attachment of a hydroxyl group to a carbonyl group. This is why the group is known as carboxyl group. Carboxylic acids can be either aliphatic or aromatic on the basis of the group present. If an alkyl group is present (RCOOH) and if an aryl group is present (ArCOOH). The higher members of the aliphatic carboxylic acids, from C12-C18 are known as fatty acids that are found in nature as natural fats or esters of glycerol. Moreover, this group is the starting material for many essential organic compounds like esters, acid chlorides, anhydrides, amides etc.
Carboxyl Group & its structure
Carboxyl group is a functional organic compound. In this structure of a carboxyl group, a carbon atom is attached to an oxygen atom with the help of a double bond. It also has a single bond to a hydroxyl group. Carboxylic acids are compound containing carboxyl structure. There are many members in this class of organic acids such as acetic acid and amino acid. Carboxyl group is generally present on the sides of the molecules. The carboxyl group ionizes and releases the H atom present in the hydroxyl group part as a free H+ ion or a proton. However, the rest of part, this is O, convey a negative charge. The charge moves in between the two oxygen molecules forward and backward thereby making the state of ionization relatively steady.

Fructose Corn Syrup Research Paper
1096 Words | 5 PagesMany people want to believe old age will kill them, but more than likely, the killer will come from what they put into their bodies. Every day, people are faced with affecting their own health. To do so, one must be conscious of what their temple receives; this means people must watch what they eat. People must look at the ingredients contained in everyday foods, what those ingredients cause to happen in the body, and the effects the ingredients have on the body, like the ingredient high fructose corn syrup. The amounts of overconsumed and unhealthy contents of high fructose corn syrup (HFCS) need to be replaced by natural sugars.
Periodic Trends Lab Report
2406 Words | 10 PagesThis means that all of the elements in the same group have a main aspect in common, except for a few exceptions. These elements react with the same specific compounds. This was used to identify the order of the groups from left to right and to determine which elements go under which group. Some research was conducted to identify all the names of the groups ranging from element number one to element number 20. Once all group names were recorded, it was researched which groups react with which compounds that are given on the element cards.
Horseradish Peroxidase Lab Report
1090 Words | 5 PagesEach amino acid is made up of an amino group, a carboxyl group and a side chain (Reece, J. B., Urry, L. (2016). Campbell biology. Boston Pearson). Enzymes work by lowering the activation energy of the reaction making the reaction produce faster. Enzymes begin to catalyze chemical reactions with the binding of the substrate to the active site on the enzyme.
Benzocaine Synthesis Lab Report
536 Words | 3 PagesThe reaction to synthesize benzocaine was known as a Fisher esterification reaction. The Fisher esterification was reaction between alcohol and carboxylic acid in the presence of acid. The reaction was used to form an ester. In the experiment, sulfuric acid acted as a catalyst and necessary for this reaction to occur. There was a change between the –OH group of carboxylic acid to an –OCH2CH3 group in the reaction.

Lab Report Scaffold: Bromination Of Trans-Cinnamic Acid
904 Words | 4 PagesChem 51 LB Experiment 3 Report Scaffold: Bromination of Trans-Cinnamic Acid 1. The goal of this experiment was to perform a halogenation reaction through the addition of two bromides from pyridinium tribromide. This was accomplished by reacting trans-cinnamic acid with pyridinium tribromide. After the reaction took place, melting point analysis was conducted to find out the stereochemistry of the product, which could either be syn-addition, anti-addition, or syn + anti-addition. 2.
Grignard Reaction Lab Report
1105 Words | 5 PagesDiscussion The purpose of this lab was to properly prepare a Grignard reagent from an unknown aryl halide and then to use the prepared Grignard reagent with solid carbon dioxide and an acid quench to form a carboxylic acid. Organometallics are compounds that have a carbon bonded to a metal; C-M, where M is any transition metal. In an organometallic, the carbon has a partial negative charge and is considered electron-rich due to the bond with the positively charged metal. Because of this partial negative charge, the carbon acts as a nucleophile and is able to be used in reactions to produce new bonds between carbon atoms by attaching to another carbon that acts as an electrophile.
Ketone Formation
387 Words | 2 Pages2- In semicarbazone formation only one of the two –NH2groups in semicarbazide undergoes nucleophilic addition to the carbonyl group. Explain the difference in the reactivity of these two –NH2 groups, using resonance structures. • Within the semicarbazone formation there are two –NH2 groups. The one closest to the ketone partakes in the electron resonance and therefore is the more stable out of the two. It doesn’t want to interrupt the p-orbital it’s sharing.

876 Words | 4 PagesIt is secreted by the oxyntic cells in the gut which are found within the oxyntic glands of the stomach lining. The substance is colourless yet remarkably corrosive, and is therefore able to be the primary digester of food in an individual4. The liquid’s pH level is a highly dangerous, yielding 1, though it may vary slightly due to its molarity (# of molesliters of solution), but nevertheless is deemed a strong acid. When the two are combined, CO2 is released, and so the their rate of reaction may be measured by the pressure of the resulting gas5.
Amino Acid Chromatography Essay
991 Words | 4 PagesAmino acid play central roles as building blocks of proteins and as intermediates in metabolisms . The 20 amino acids are found within proteins convey a vast array of chemical versatility (The Biology Project.2000).All amino acids found in proteins have a basic structure , different only in the structure of the R group or the side chain(Figure). In this basic structure amino acid (Figure 4 ) is containing a central C atom , in sides a H atom, an amino group, a carboxyl group and the R group. The amino acid can be recognized based on this R group .

1071 Words | 5 PagesMefenamic acid A Complete Guide on Taking Mefenamic Acid Mefenamic acid is a common medication used to treat various types of pain. It belongs to a group of drugs called non-steroidal anti-inflammatory drugs (NSAIDs), which is typically taken by mouth. It works by reducing your body's production of an inflammatory substance that causes fever, swelling and pain. Part 1: Precautions Before Taking Mefenamic Acid Although mefenamic acid is a medication that may be bought over-the-counter, there are some things to keep in mind before taking it, including: • Tell your doctor/pharmacist if you are allergic to mefenamic acid, aspirin or other NSAID such as ibuprofen or naproxen.
Benzoic Acid Lab Report
767 Words | 4 PagesAbstract The unknown concentration of benzoic acid used when titrated with standardized 0.1031M NaOH and the solubility was calculated at two different temperatures (20◦C and 30◦C). With the aid of the Van’t Hoff equation, the enthalpy of solution of benzoic acid at those temperatures was determined as 10.82 KJ. This compares well with the value of 10.27KJ found in the literature.

1098 Words | 5 PagesIntroduction: In this experiment acid base indicators will be tested, using a red cabbage mixture. Substances can be classified as acidic or alkalinic depending on the concentration of hydrogen or hydroxide ions. The higher the concentration of hydrogen ions the lower the pH this means it will be an acid and the higher the concentration of hydroxide ions the higher the pH this means it will be an base(science prof online).
