The carbonyl stretch C=O of aliphatic esters appears from 1750-1735 cm-1; that of α, β-unsaturated esters appears from 1730-1715 cm-1. See also: carbonyl stretching frequencies. The C–O stretches appear as two or more bands in the region 1300-1000 cm-1. Summary: C=O stretch aliphatic from 1750-1735 cm-1; α, β-unsaturated from 1730-1715 cm-1 An additional molecular geometry is centered on the oxygen of the - OH group. This is BENT.

While carboxylic acid has the -COOH group, the hydrogen is replaced by a hydrocarbon in an ester. Benzyl acetate has an ester functional group (in red), an acetyl moiety (circled with dark green) and a benzyloxy moiety (circled with light orange). Other divisions can be made. In organic chemistry , a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions . esters are chemical compounds derived from an acid (organic or inorganic) in which at least one -OH (hydroxyl) group is replaced by an -O-alkyl (alkoxy) group.

Key Points Esters are a functional group commonly encountered in organic chemistry. They are characterized by a carbon bound to Ester names are derived from the parent alcohol and the parent acid. While simple esters are often called by their Esters react with nucleophiles at the carbonyl 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.
