  2. Basic Structure • Carboxylic acid is a hydrocarbon containing carboxyl. • Carboxylic acid forms 4 bonds in its neutral state which may be in the form of single bonds, or a mixture of single and multiple bonds. • carbon forms a double bond to an oxygen atom forming a carbonyl moiety. • Carbonoxylic acid structure has many unique chemical properties resulting from the combination of the different moieties that are in its structure. Ex: acidic

  3. Characteristics • All carboxylic acids are compounds which contain a –COOH group • The hydrogen in this group makes the compound acidic • In water the acid does not dissolve and instead the hydrogen molecules bond with the water creating a new substance

  4. Boiling Points • The boiling point of all carboxylic acids is determined by the ability to form hydrogen bonds • Alcohols for example have higher boiling point than alkanes because their hydrogen bonds are similar in size and from bonds easier • Carboxylic acids boiling point is still higher though

  5. Nomenclature • Carboxylic acids are named by dropping the -e ending of the parent name and adding -oic . • The name for a -COOH group is carboxy. Pentanoic acid

  6. Nomenclature • When one or more –COOH groups are attached to a ring, the ring is named followed by the word -carboxylic acid. cyclobutanecarboxylic acid

  7. Nomenclature • Salts of carboxylic acids are named by first naming the metal, followed by a space and then by changing the name of the acid by dropping the -oic acid ending and adding -oate. sodium benzoate

  8. Mechanisms • Methyl ester formation- Methyl esters are often prepared by the reaction of carboxylic acids with diazomethane.

  9. Mechanisms cont. • Acid halide formation- Carboxylic acids react with phosphorous trichloride (PCl3), phosphorous pentachloride (PCl5), thionyl chloride (SOCl2), and phosphorous tribromide (PBr3) to form acyl halides.

  10. Mechanisms cont. • Acid anhydride formation- This group forms by reacting the salt of a carboxylic acid with an acyl halide.

  11. Examples • Formic acid is used as a chemical solvent, and as a disinfectant. It is also used in processing textiles and leathers, and latex rubber. • Propionic Acid naturally occurs in sweat and milk as result of bacterial fermentation • Butryic Acid occurs in butter and creates a smell in butter when it has gone sour • Caporic Acid is in animal fats and oils and is manufactured to use in pharmaceuticals and flavorings

  12. Real World Importance • Without carboxylic many everyday items would be out of use • With their use in pharmaceuticals such as aspirin the absence of carboxylic acid would not allow people to relieve pain and would stop the easy prevention of heart attacks • Carboxylic acids are also the main ingredients in sunscreen

  13. Real World Importance • Without aspirin people would not be able to prevent heart attacks and blood clots which would lead to more deaths • Carboxylic acid also lets us know when dairy products have gone bad which is essential for cooking
