Some other Properties of Ester: Esters are neutral(do not change color of litmus, phenolphthalein, methyl orange or any other acid- base indicator) compounds Esters are colorless and exist in liquid state at room temperature Esters are polar due to the presence of carbonyl (=C=O)group and act as hydrogen bond acceptors not as donors. Esters are volatile in nature and have low boiling and melting points.

esters Esters represent the largest group of flavor compounds in alcoholic beverages, generating the “fruity” aromas in beer (not including, of course, the direct addition of fruit and fruit flavors in certain beers). The esters are formed by the reactions of organic acids and alcohols created during fermentation. • Describe the uses of esters.

In chemistry, an ester is a chemical compound derived from an acid (organic or inorganic) in which at least one –OH (hydroxyl) group is replaced by an –O– alkyl (alkoxy) group. Usually, esters are derived from a substitution reaction of carboxylic acid and an alcohol.

Esters can be cleaved back into a carboxylic acid and an alcohol by reaction with water and a base The reaction is called a saponification from the Latin sapo which means soap. The name comes from the fact that soap used to me made by the ester hydrolysis of fats. Due to the basic conditions a carboxylate ion is made rather than a carboxylic acid.

R 1 and R 2 are often carbon chains that can be either linear or branched and might also have other functional groups attached.
