Lab 1 Synthesis of Banana Oil Esters belong to a class of compounds widely found in nature. The flavors and aromas in fruits and flowering plants are generally due to complex mixtures that include esters, carboxylic acids, alcohols, ketones and aldehydes, and several hydrocarbons. However, some natural aromas and flavors are due to a single ester; examples include rose flower, raspberry, pineapple and banana. Esters are derived from a carboxylic acid and an alcohol. The ester functional group has two oxygen atoms, the carbonyl oxygen which comes from a carboxylic acid, and the alkoxy oxygen which comes from the alcohol. In like manner, esters have two-word names, the first name from the alcohol (named as the alkyl group) and the second name from the parent acid in which the oic suffix is changed to oate. As an example, consider how the
