The term 'Banana Oils, for example' is referring to esters, which are a type of chemical compound composed of an acid and an alcohol. Esters are formed when the hydrogen atom in the carboxylic acid reacts with the hydroxyl group in the alcohol, forming an oxygen bridge between them. They are found in many everyday products, such as perfumes, flavorings, and solvents. Banana oils are a specific type of ester, which are used in the production of artificial banana flavoring.
