Reaction of ester with alcohol

WebThe condensation reaction of an alcohol with a carboxylic acid produces an ester by losing a water molecule. This chemical reaction is known as esterification. Esters are represented by a general formula C n H 2n+1 COOC n H 2n+1 or R-COO-R ’ where R and R ’ denote alkyl chains attached on either side of the ester linkage. WebEsterification can happen in three ways. They are discussed below: From acid anhydride and alcohol From acid chloride and alcohol From carboxylic acid and alcohol 1. Acid …
