https://en.wikipedia.org/wiki/Ester
An ester of a carboxylic acid.R stands for any group (typically hydrogen or organyl) and R ′ stands for any organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).Analogues derived from oxygen replaced by other chalcogens

The ester is therefore butyl propionate or butyl propanoate. An alkyl group (in green) is attached directly to the oxygen atom by its middle carbon atom; it is an isopropyl group. The part derived from the acid (that is, the benzene ring and the carbonyl group, in red) is benzoate. The ester is therefore isopropyl benzoate (both the common name

An ester is hydrolyzed, either by aqueous base or aqueous acid, to yield a carboxylic acid plus an alcohol. Ester hydrolysis in basic solution is called saponification, after the Latin word sapo, meaning "soap.". We'll see in Section 27.2 that soap is in fact made by boiling animal fat with aqueous base to hydrolyze the ester linkages.

Ester saponification in biological systems, called hydrolytic acyl substitution reactions, are common. In particular, acetylcholinesterase, an enzyme present in the synapse, catalyzes hydrolysis of the ester group in acetylcholine which is a neurotransmitter that triggers muscle contraction. Like many other hydrolytic enzymes, the

Esters contain a carbonyl group with a second oxygen atom bonded to the carbon atom in the carbonyl group by a single bond. In an ester, the second oxygen atom bonds to another carbon atom (Figure 25.5a.). The names for esters include prefixes that denote the lengths of the carbon chains in the molecules and are derived following nomenclature rules similar to those for inorganic acids and salts.

The ester with the common name "ethyl crotonate" has the formula CH₃CH=CHCOOCH₂CH₃. There is a trans C=C double bond between C-2 and C-3 of the acid portion of the ester. The acid itself is named but-2-enoic acid. We could indicate stereochemistry by calling it trans-but-2-enoic acid, but the Cahn-Ingold-Prélog E/Z notation is preferred.

An ester bond is a linkage between an atom that is double bonded to an oxygen atom bearing any alkyl or aryl group. Ester bonds are found in ester functional groups. In addition, the bond is generally covalent and is essential in the formation of lipids. Example of an Ester Bond. Image source: What is an ester bond?

An ester can be thought of as a product of a condensation reaction of an acid (usually an organic acid) and an alcohol (or phenol compound), although there are other ways to form esters. Condensation is a type of chemical reaction in which two molecules are joined together and eliminate a small molecule, in this case two-OH groups are joined eliminating a water molecule.

The Ester functional group is a carboxylic acid derivative that is analogous to the Amides that were highlighted in Amide Functional Group Spotlight, but contain an Oxygen atom instead of a Nitrogen. While this may seem like a very small change, there are some important consequences for stability and reactivity which we will cover.

An ester is a chemical compound derived from an acid (organic or inorganic) in which at least one -OH hydroxyl group is replaced by an -O- alkyl (alkoxy) group. To put it in simple terms, esters are a group of chemical compounds which are formed by bonding of an alcohol group with a group of organic acids, by losing water molecules.

An ester is an organic compound that is a derivative of a carboxylic acid, in which the hydrogen atom of the hydroxyl group has been replaced with an alkyl group. The structure is the product of a carboxylic acid (the R R -portion) and an alcohol (the R′ R ′ -portion). The general formula for an ester is shown below.

Esters. An ester is an organic compound that is a derivative of a carboxylic acid. While esters occur naturally, they are easily synthesized by reacting an alcohol (shown in red) with a carboxylic acid (shown in blue): Note that the structure of the carboxylic acid was flipped 180º to show the carboxyl group on the left, so it is easier to see

The ester is the only thing in the mixture which doesn't form hydrogen bonds, and so it has the weakest intermolecular forces. Larger esters tend to form more slowly. In these cases, it may be necessary to heat the reaction mixture under reflux for some time to produce an equilibrium mixture. The ester can be separated from the carboxylic acid
