Ester

An ester is a type of chemical compound formed when an acid reacts with an alcohol, resulting in a molecule with a distinctive pleasant smell. They are commonly found in natural sources such as fruits and flowers, contributing to their aroma. In addition to their role in nature, esters are used in products like perfumes, flavorings, and solvents. Chemically, esters have a specific structure characterized by a carbon atom double-bonded to an oxygen atom and single-bonded to another oxygen atom, which connects to the rest of the molecule.
