How do you name a branched ester?
Esters can be named using a few steps Esters are named as if the alkyl chain from the alcohol is a substituent. No number is assigned to this alkyl chain. 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.
What are the names of esters?

- change the name of the parent alcohol to end in –yl.
- change the name of the parent acid to end in –oate.
- alcohol name goes to the front, acid name to the back.
What are cyclic esters?
A lactone or cyclic ester is a carboxylic acid ester in the molecule of which the ligand on the carbonyl carbon and that on the oxygen atom are linked by one or more carbon chains.
What is the prefix of an ester?
463.3 – Ester groups in compounds are named (a) by use of a prefix “alkoxycarbonyl-” or “aryloxycarbonyl-“, etc., for the group when the radical R1 contains a substituent with priority for citation as principal group, or (b) by use of a prefix “acyloxy-” for the group when the radical contains a substituent with …
What is the IUPAC nomenclature?
IUPAC nomenclature is based on naming a molecule’s longest chain of carbons connected by single bonds, whether in a continuous chain or in a ring. All deviations, either multiple bonds or atoms other than carbon and hydrogen, are indicated by prefixes or suffixes according to a specific set of priorities.
What prefix is used for ester?
How are lactones named?
Lactones are generally named after the carboxylic acid by using the suffix -lactone. A Greek letter is used to indicate the ring size. Thus, all γ-lactones have five-membered rings and all ε-lactones have seven-membered rings.
