On the IUPAC nomenclature of ethers and esters

[QUOTE="fakecop, post: 4655397, member: 484754"] Hello, I was wondering if there is a systematic procedure to follow when naming complex organic molecules containing ethers and esters. By "complex" I mean organic molecules that contain multiple ether/ester groups and possibly within multiple different branches of the molecule. 1.How to determine the alkoxy/alkyl groups when there are multiple ether linkages in the molecule? E.g. CH2---O---CH2CH3CH2---O---CH3CH2CH2---O---CH2 -Similarly, how to name the alkyl group when there are multiple ester groups in the molecule? E.g. CH3---COO---CH2CH3CH2---COO---CH3 2.How to name the alkoxy group when it contains an aldehyde or carboxylic acid? E.g. COOH---CH2---O---CH2---COOH I'm guessing that I'd have to switch to prefix notation, so the compound above would be called "2-carboxymethoxyethanoic acid" or "dicarboxymethyl ether"? If that is the case, how would you name the ether if the carboxyl/oxo group is [B]directly[/B] attached to the Oxygen, like this: COOH --O -- COOH or CHO --O --CHO ? 3. How do you name aldehydes/carboxylic acids joined by an ester? E.g. CHO---CH2---COO---CH2---COOH So now do I have to switch to prefix form for both groups? Thus, would this molecule be named "carboxylmethyl 3-oxopropanoate"? My textbook and most sources on the internet only covers the simple stuff. Please help me. (I apologize for the messy diagrams but there is no LaTex symbols for organic chemistry) [/QUOTE]
