There are three functional group isomers of which you need to be aware: alcohols and ethers; aldehydes and ketones; carboxylic acids and esters
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 A carboxylic acid contains the -COOH group, and in an ester the hydrogen in this group is replaced by a hydrocarbon group. This could be an alkyl group like methyl or ethyl, or one containing a benzene ring such as a phenyl or benzyl group. The most commonly discussed ester is ethyl ethanoate. In organic chemistry, the most common functional groups are carbonyls (C=O), alcohols (-OH), carboxylic acids (CO 2 H), esters (CO 2 R), and amines (NH 2).
The carboxyl group is a functional group that contains a carbon–oxygen Polarity Ranking of the Functional Groups: (most polar first). Amide > Acid > Alcohol > Ketone ~ Aldehyde > Amine > Ester > Ether > Alkane.

The ester An organic compound derived from a carboxylic acid and an alcohol in which the OH of the acid is replaced by an OR group., which is organic compound derived from a carboxylic acid and an alcohol in which the OH of the acid is replaced by an OR group, looks somewhat like an ether and also somewhat 2020-04-07 · The hydroxyl group indicates that an OH, or hydroxide, has bonded to a carbon.The carbonyl double bond, two carbons bonded to each other, has an OH bond attached to each end of its two carbons. Last, its ester functional group indicates where two oxygen groups are bonded to a carbon. This ketone occurs because dilute sodium hydroxide has sufficient strength to hydrolyze the ester functional group but insufficient strength to hydrolyze the ketone functional group.
