Ester 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, as in the substitution reaction of a carboxylic acid and an alcohol. Glycerides are fatty acid esters of glycerol; th...
An ester group needs two oxygen atoms and two carbon atoms to complete its characteristic structure while an ether group needs only one Oxygen atom and two Carbon atoms for its structure. The various other differences between ether and ester are given he

Ester oil is made from alcohol and carboxylic acids. Water is a byproduct of this esterification reaction. Since all the esterification reactions are reversible, water can break ester back into the acid and alcohol components. What is the Difference Between Pag Oil and Ester Oil?
Science vs Art The difference between science and art stems from the nature of the subjects studied. Now, it seems so easy and almost natural to beli
What are the Similarities Between Arachidic Acid and Arachidonic Acid? Arachidic acid and arachidonic acid are two structurally similar fatty acids. Both fatty acids contain a C-20 chain. They are carboxylic acids. They are present in natural food sources. ...
