Carboxyl carboxylate. ester name ending

The esters name usually comes from the acid and ends in the suffix ate as does the word acetate itself. The acetate group is made from acetic acid by replacing the carboxyl hydrogen with an 7 group ... 

The first word of the name of an ester is the name of the alkyl or aromatic group (R ) contributed by the alcohol. The second word is the carboxylic acid name, with the -ic acid ending changed to -ate. This is similar to the method used for naming carboxylic acid salts. Thus, an ester of acetic acid becomes an acetate, one of butyric acid becomes a butyrate, one of lactic acid becomes a lactate, and so on. 

Esters are named by replacing the ending -ic acid with the suffix -ate. The alcohol portion of the ester is named by replacing the -ane ending of the parent hydrocarbon name with the suffix -yl. The alkyl radical name of an ester is separated from the carboxylate name, eg, methyl formate for HCOOCH. Amides are named by changing the ending -oic acid to -amide for either systematic or common names, eg, hexanamide and acetamide. 

Esters are named by first identifying the alkyl group attached to oxygen and then the carboxylic acid, with the -ic acid ending replaced by -ate. 

Thioesters are named like the corresponding esters. If the related ester has a common name, the prefix thio- is added to the name of the carboxylate acetate becomes thioacetate, for instance. If the related ester has a systematic name, the -oate or -carboxylate ending is replaced by -thioate or -carbothioate butanoate becomes butanelhioate and cyclohexanecarboxylate becomes cyclohexane-carbothioate, for instance. 

The names of esters consist of two words that reflect their formation from an alcohol and a carboxylic acid. According to the 1UPAC rule. Ihe alkyl or aryl group of the alcohol is cited first followed by the carboxylate group of the acid with the ending -ate replacing the -ic of the acid. For example. CHiCHiCOOCH, the methyl ester of propanoic acid, is called methyl propanoate (or methyl propionate, if the trivial name, propionic acid, is used for the carboxylic acid). 

Since esters are derived from carboxylic acids and alcohols, they are named by first identifying the alcohol-related part and then the acid-related part, using the -ate ending. Ethyl acetate, for example, is the ester derived from ethanol and acetic acid. 

Salts and Esters of Acids. Neutral salts of acids are named by citing the cation(s) and then the anion, whose ending is changed from -oic to -oate or from -ic to -ate. When different acidic residues are present in one structure, prefixes are formed by changing the anion ending -ate to -ato- or -ide to -ido-. The prefix carboxylato- denotes the ionic group —COO-. The phrase (metal) salt of (the acid) is permissible when the carboxyl groups are not all named as affixes. 

One important group of condensation polymers is the polyesters. The most important commercial polyester is formed from the reaction of terephthalic acid (a diacid) with ethylene glycol (a diol). This polymerization occurs in a stepwise fashion (hence the name step growth polymerization). First, one carboxylic acid group of a diacid molecule and one hydroxy group of a diol molecule combine to form an ester, with the loss of water. Then a second diol molecule reacts with the unreacted caiboxylic group on the other end of the diacid molecule, or a second diacid molecule reacts with the unreacted hydroxy group of the diol. Continuation of this process adds a new monomer unit at... 

Two amphiphiles with a reactive dye system as head groups, namely p-phenylenediamine and 4,4 -bipyridinium salts, have already been mentioned. Other such membrane-forming amphiphiles were modelled following natural photosynthetic membrane systems. Carotenoid amphiphiles are accessible from the cheap natural bolaamphiphile bixin, which carries a carboxylic acid on one end and a methyl ester on the other. A variety of orange-coloured bolaamphi-... 

Esters are named by stating the name of the alkyl group of the alcohol (the methyl group in this case), followed by the name of the carboxylic acid with the ending -ate (acetate). One of the most important esters in commercial production is vinyl acetate, with the structure... 

The nomenclature of esters is similar to the nomenclature of the carboxylic acid salts. The alkyl group bonded to the oxygen atom is named first, then the -ic acid ending of the corresponding carboxylic acid is changed to -oate. 

Like carboxylic acids, esters are often referred to by their common names. The name consists of the alkyl name from the alcohol followed by the acid name, where the -ic ending is replaced by -ate. For example, the ester... 

Esters are alcohol derivatives of carboxylic acids. They are named in much the same way as salts. The alcohol part (R in OR ) is named first, followed by the name of the acid modified to end in -ate. The -ic ending of the organic acid name is replaced by the ending -ate. Thus in the lUPAC system, ethanoic acid becomes ethanoate. In the common names, acetic acid becomes acetate. To name an ester, be sure to recognize the portion of the ester molecule that comes from the acid and the portion that comes from the alcohol. In the general formula for an ester, the RC=0 comes from the acid and the R O comes from the alcohol ...
