The name is based on the acid followed by the suffix “-oate”. While simple esters can be named after their common names, all esters can be named using their systematic IUPAC name. The name of an ester derives from the parent alcohol and parent acid. Their ability to participate in hydrogen bonding depends on the length of the alkyl chains attached to the ester functional group. Due to the polar property of esters, they can participate in hydrogen bonding as hydrogen bond acceptors. In comparison to alcohols and carboxylic acids, esters tend to be polar less allowing for them to have lower boiling points. This process is what causes ester bonds to form. When glycerol (alcohol) combines with fatty acid molecules, it allows for three esters to be produced. These ester bonds are important when it comes to lipids in our bodies. In addition, the bond is generally covalent and is essential in the formation of lipids. Ester bonds are found in ester functional groups. What is an Ester Bond?Īn ester bond is a linkage between an atom that is double bonded to an oxygen atom bearing any alkyl or aryl group. The R groups denote the rest of the molecule not included in the functional group. The basic chemical formula of an ester is R-COOR’. Basic Ester Structure with lone electron pairs For the molecule below, the simple structure of an ester group is shown. The basic structure of an ester consists of a carbon single bonded to carbon, double bonded to oxygen, and single bonded to oxygen. In organic chemistry, esters are a common functional group. You will also learn about esterification and its mechanism. In this tutorial you will learn about the basic properties and structure of an ester functional group.
