Does the carboxyl group need to be on the end?

Is ethanoic pronounced eeth-an-oyk, or eth-an-oh-ic?

CO at OH
SEF Posted Aug 30, 2003
NB There isn't anything mysterious about COOH only being at the end of a chain. It is simply that the carbon has run out of covalent bonds (outer shell electrons to make pairs). C has 4 possible bonds (unpaired electrons). The O uses 2 of them and the OH another 1 (that O uses 1 for the C and 1 for the H). This only leaves 1 to connect to something else, eg H or another C.
