A carboxylic acid is an organic compound that contains the carboxyl functional group. The general formula for a carboxylic acid can be abbreviated as \(\ce{R-COOH}\). Many carboxylic acids are used in the food and beverage industry for flavoring and/or as preservatives. An ester has an OR group attached to the carbon atom of a carbonyl group.

2020-01-04 · 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. While carboxylic acid has the -COOH group, the hydrogen is replaced by a hydrocarbon in an ester.

Esters are a functional group commonly encountered in organic chemistry. They are characterized by a carbon bound to three other atoms: a single bond to a carbon, a double bond to an oxygen, and a single bond to an oxygen. The singly bound oxygen is bound to another carbon. Ester names are derived from the parent alcohol and the parent acid.
