An example of an ester formation is the substitution reaction between a carboxylic acid (R−C (=O)−OH) and an alcohol (R'−OH), forming an ester (R−C (=O)−O−R'), where R stands for any group (typically hydrogen or organyl) and R ′ stands for organyl group.
Ester, any of a class of organic compounds that react with water to produce alcohols and organic or inorganic acids. Esters derived from carboxylic acids are the most common. Learn about the different types and reactions of esters and more in this article.
An ester is an organic compound where the hydrogen in the compound's carboxyl group is replaced with a hydrocarbon group. Esters are derived from carboxylic acids and (usually) alcohol.
Key Takeaway An ester has an OR group attached to the carbon atom of a carbonyl group.
An ester is an organic compound formed when a carboxylic acid reacts with an alcohol, a process known as esterification. This reaction involves the removal of a water molecule.
The general structure of an ester is RCOOR', where R and R' represent alkyl or aryl groups. Esters are derived from the condensation reaction between a carboxylic acid and an alcohol, resulting in the elimination of water.
Esters are also the building blocks for an important class of polymers known as polyesters. These materials, characterized by repeating ester linkages in their molecular chains, are widely used in textiles, such as polyethylene terephthalate (PET) fibers, and in the production of plastic bottles.
Ester hydrolysis in basic solution is called saponification, after the Latin word sapo, meaning “soap.” We’ll see in Section 27.2 that soap is in fact made by boiling animal fat with aqueous base to hydrolyze the ester linkages.
