![Carboxylic acid<br />Introduction <br />CARBOXYLIC ACIDS : <br />are organic acids characterized by the presence of at least one carboxyl group. The general formula of a carboxylic acid is R-COOH, where R is some monovalent functional group. A carboxyl group (or carboxy) is a functional group consisting of a carbonyl (RR'C=O) and a hydroxyl (R-O-H), which has the formula -C(=O)OH, usually written as -COOH or -CO2H.<br />SOLUBILITY :<br />Carboxylic acids are polar .the Smaller carboxylic acids (1 to 5 carbons) are soluble with water, whereas higher carboxylic acids are less soluble due to the increasing hydrophobic nature of the alkyl chain<br />BOILING POINTS : <br />Carboxylic acids tend to have higher boiling points <br />ACIDITY :<br />Carboxylic acids are typically weak acids, meaning that they only partially dissociate into H+ cations and RCOO– anions in neutral aqueous solution. For example, at room temperature, only 0.4% of all acetic acid molecules are dissociated. Electronegative substituents give stronger acids.<br />ODOR :<br />Carboxylic acids often have strong odors, especially the volatile derivatives. Most common are acetic acid (vinegar) and butyric acid (rancid butter). <br />GENERAL UESES:<br />Carboxylic acids are used in the production of polymers, pharmaceuticals, solvents, and food additives. Industrially important carboxylic acids include acetic acid (component of vinegar, precursor to solvents and coatings), citric acid (beverages), fatty acids (coatings), maleic acid (polymers), propionic acid (food preservative), <br />SYNTHESIS :<br /> Industrial routes.<br />,[object Object]](https://image.slidesharecdn.com/carboxylicacid-110424191244-phpapp01/85/Carboxylic-acid-1-320.jpg)

- 3. Oxidative cleavage of olefins by ozonolysis, potassium permanganate, or potassium dichromate.
- 4. Carboxylic acids can also be obtained by the hydrolysis of nitriles, esters, or amides, generally with acid- or base-catalysis.

- 8. For some people, aspirin does not have as strong an effect on platelets as for others, an effect known as aspirin resistance or insensitivity
- 10. Vitamin C may also be useful in lowering serum uric acid levels resulting in a correspondingly lower incidence of gout,[123]
- 11. and an oxidized version that can cross the blood-brain barrier may reduce neurological deficits and mortality following a stroke
- 12. Vitamin C's effect on the common cold has been extensively researched and has not been shown effective in prevention or treatment of the common (viral) cold
- 14. Vitamin C is the most widely taken dietary supplement. It is available in caplets, tablets, capsules, drink mix packets, in multi-vitamin formulations, in multiple antioxidant formulations, and crystalline powder
