An ester is a organic functional group made up of a carbonyl and an alkoxy.

Ester name of functional group. Propanone or acetone common name Acid -oic acid. Names and Structures of simple Linear Estersin which R2 CH 2 CH 3 which is known as an -ethyl group. A Identify the alkyl chain making up the carboxylic acid.

A Identify the alkyl group that has replaced the H of the carboxylate group. A common ester - ethyl ethanoate The most commonly discussed ester is. This is followed by the name of the parent chain from the carboxylic acid part of the ester with an e remove and replaced with the ending oate.

Esters are named as if the alkyl chain from the alcohol is a substituent. Esters are a functional group commonly encountered in organic chemistry. Due to unshared electrons on oxygen esters are comprised of two resonance structures which contribute to its stability.

Locate the ester COO functional group. The following table shows the first six members of the homologous series of linear esters that include an -ethyl group attached via a single covalent bond to the oxygen atom in the chain of the ester. The alcohol functional group is -.

The good is that esters follow the same pattern and instead of the metal ion we use the alkyl group connected. B Name this alkanoic acid. Functional group is an ester therefore suffix -oate The alcohol component here is 2-propanol or isopropanol so the alkyl 2-propyl or isopropyl The acid component has a longest continuous chain that is C4 so the root but With the acid group at C1 there is a methyl group at C2 2-methyl.

KEY POINTS Esters are a functional group commonly encountered in organic chemistry. If attached to an alkyl group R this becomes R - CO2H. They are characterized by a carbon bound to three other atoms.
