15 Σεπ 2022 · Identify the general structure for an ester. Use common names to name esters. Name esters according to the IUPAC system. Esters have the general formula RCOOR ′, where R may be a hydrogen atom, an alkyl group, or an aryl group, and R′ may be an alkyl group or an aryl group but not a hydrogen atom.

What is an Ester Functional Group? In organic chemistry, esters are a common functional group. The basic structure of an ester consists of a carbon single bonded to carbon, double bonded to oxygen, and single bonded to oxygen. For the molecule below, the simple structure of an ester group is shown. Basic Ester Structure with lone electron pairs
Esters are one of the more useful functional groups. Their low reactivity makes the easy to work with and they are stable enough to be used as a solvent in organic reactions (ex. ethyl acetate). Esters are still reactive enough to undergo hydrolysis to form carboxylic acids, alcoholysis, to form different esters, and aminolysis to form amides.
An example of an ester formation is the substitution reaction between a carboxylic acid (R−C (=O)−OH) and an alcohol (R'−OH), forming an ester (R−C (=O)−O−R'), where R stands for any group (typically hydrogen or organyl) and R ′ stands for organyl group.

14 Ιουλ 2021 · Esters feature a carbon-to-oxygen double bond that is also singly bonded to a second oxygen atom, which is then joined to an alkyl or an aryl group. The esters shown here are ethyl acetate (a) and methyl butyrate (b).
The functional groups for an ester are shown in red below. Figure 25.5a. Condensed structural formula for an ester highlighting the carbonyl group and a single oxygen bonded to another carbon (credit: Chemistry (OpenStax), CC BY).
