Esterfication of acids with multiple acidic groups


how does one name esters of organic acids that have multiple acidic functional groups (ex citric acid)? what would it be called with say, 1 of those groups "esterfied"? what about two? what about all three?

Well, I'm not sure but...
There is certainly a chemical called triethyl citrate. There must be two different diethyl citrates and two monoethyl citrates.
I presume that the diesters would be called 1,3 diethyl citrate and 1,5 diethy citrate and that the mono esters would be 1 ethyl and 3 ethyl citrate.
There is still the question of things like 1-ethyl, 3-propyl 5-butyl citrate whch would exist in R and S forms.
At least, that's my best guess, has anyone else got any ideas?

That's right. The original poster needs to look up some info on Google on the subject of "chemical nomenclature".

Not any more, he doesn't.:)

The rules for IUPAC organic nomenclature are given in the CRC handbook. They run to about 40 pages and are rather daunting to the uninitiated.
