WebAnswer (1 of 2): In naming coordination compounds, the prefixes di (=2), tri (=3), tetra (=4) etc is used to specify simple unidentate ligands bonded to the metal. For complicated ligands (polydentate chelating agents) prefixes such as bis (=2), tris (=3),tetrakis (=4) etc is used. For example co... WebThe isopropyl groups are on C4 and C5, so we say 4,5-diisopropyl. If you are naming the isopropyl groups by their official name of 1-methylethyl, you must use the IUPAC rule, which state that the multiplying prefix for two of a complex group (a group with locant in the name), must be bis. So, we say bis- (1-methylethyl).
