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.
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.
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.
Key Takeaway An ester has an OR group attached to the carbon atom of a carbonyl group.
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.
The presence of a carbonyl group (C=O) adjacent to an ether-like linkage (C-O-C) defines the ester functional group, giving esters their characteristic chemical behavior and physical properties.
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.
The process of creating esters occurs through an esterification reaction, where a carboxylic acid reacts with an alcohol, resulting in the formation of an ester and water.
