OBS

The prefixes "ortho-," "meta-" and "para-," along with their corresponding abbreviations ("o-," "m-" and "p-"), appear in italics and are ignored in alphabetizing. According to the actual chemical nomenclature rules in organic chemistry (in 2003), the numbers designating the positions of the disubstitution groups (1,2- for "ortho-," 1,3- for "meta-" and 1,4- for "para-") are to be preferred to the symbols "o-," "m-" and "p-." Furthermore, the prefixes "ortho-," "meta-" and "para-" should not be used anymore, and their corresponding abbreviations ("o-," "m-," and "p-") will soon be judged to be avoided, if not totally condemned.
