Important Topics for MS Chauhan Organic Chemistry Solutions Chapter 9 Carboxylic Acids & their Derivatives

Carboxylic Acids
A carboxylic acid is an organic composite that consists of a carboxyl group (C(=O)OH). The universal formula of a carboxylic acid is R–COOH, where R denoting to the alkyl group. Carboxylic acids happen extensively. Significant examples comprise acetic acid and amino acids.

The Naming of Carboxylic Acids

The IUPAC name of a carboxylic acid is generated from that of the extensive carbon chain that consists of the carboxyl group by reducing the finale from the naming of the parent alkane and adding the suffix -oic surveyed by the word “acid.” The chain is calculated starting with the carbon of the carboxyl group.

Fischer Esterification

Fischer esterification is also known as Fischer–Speier esterification. It is a distinct type of esterification by depreciating a carboxylic acid and an alcohol in the existence of an acid catalyst. The reaction was first defined by the author Emil Fischer and Arthur Speier in 1895.

Acid Chloride Formation

Carboxylic acids respond with Thionyl Chloride (SOCl2) to produce acid chlorides. During this reaction process, the hydroxyl group of the carboxylic acid is transformed into a chlorosulfite intermediate creating an improved leaving group. The chloride anion formed during the reaction turns a nucleophile.


Decarboxylation refers to a chemical reaction that eliminates a carboxyl group and discharges carbon dioxide. Generally, decarboxylation denotes a reaction of carboxylic acids, eliminating a carbon atom from a carbon chain.


In organic chemistry, an ester refers to a chemical compound that is generated from an acid in which at least one –OH group is substituted by an –O–alkyl group. Generally, esters originate from a carboxylic acid and an alcohol.

Uses of Carboxylic Acid

Carboxylic acids make up a sequence of fatty acids that are tremendously beneficial for human health. The omega-3 and omega-6 are vital fatty acids which are not created by the body. They help in preserving the cell membrane and governor nutrient use along with the metabolism of the body. If we eat a meal with unsaturated fat, the nutrients and the glucose available in the meal will directly blast into the circulation without being engrossed. However, if there is a consumption of saturated fat, the rate of absorption will decrease and the body will get more time to engross the energy and nutrients from the meal.

The points described below will release other vital uses of carboxylic acids:

  • Development of soaps requires a large number of fatty acids. Soaps are usually sodium or potassium salts of greater fatty acids including stearic acid.
  • The food industry requires several organic acids for the manufacture of food products, soft drinks, etc. For example, acetic acid is required in the creation of vinegar. Sodium salts of organic acids discover application in preservatives.
  • In the medical industry, organic acids are required in the creation of many drugs including aspirin, phenacetin, etc.
  • Acetic acids are generally required as a coagulant in the development of rubber.
  • Organic acids require enormous application in creating dyestuff, perfumes, and rayon.

Reductions of Carboxylic Acid Derivatives

The reductions of carboxylic acids result in the generation of primary alcohols. These reductions are usually approved by using a tough reducing agent including lithium aluminium hydride (LiAlH4). If required, one can also use diborane (B2H6) for the reduction of carboxylic acids to alcohols.
