Esters. Esters are formed by the condensation reaction between an alcohol and a carboxylic acid. This is known as esterification. In a condensation reaction, two 

A carboxylic acid contains the -COOH group, and in an ester the hydrogen in this group is replaced by a hydrocarbon group of some kind. This could be an alkyl group like methyl or ethyl, or one containing a benzene ring like phenyl. A common ester - … 2013-10-02 2020-07-26 47 rows 2013-11-09 Esters are organic chemical compounds whose structure has the general form: where the symbols R1 and R2 represent organic radicals. R 1 and R 2 are often carbon chains that can be either linear or branched and might also have other functional groups attached. 2018-10-01 Esters are chemical compounds derived by reacting an oxoacid with a hydroxyl compound such as an alcohol or phenol.

Usually, esters are derived from a substitution reaction of carboxylic acid and an alcohol.

Introduction. Esters are formed through reactions between an acid and an alcohol with the elimination of water. An example of this is the reaction of acetic acid with an alcohol, which yields an acetic ester and water. The part enclosed by the red circle represents the ethyl group from the alcohol and the part enclosed by the green rectangle
