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).
