-oate
The suffix -oate is the IUPAC nomenclature used in organic chemistry to form names of compounds formed from carboxylic acids. They are of two types:
- Formed by replacing the hydrogen atom in the –COOH by some other radical, for example methyl benzoate CH–CO–OCH
- Formed by removing the nucleus ( proton) of the hydrogen atom in the –COOH, producing an anion: then add a cation, for example sodium benzoate CH–CO–O Na
The suffix is derived from " -oic acid".
The most common example of compounds with sufix "oate" are Ester which contain organic compounds with suffix "oate". Example - Ethyl acetate of formula - CH3-COO-CH2-CH3
