But students face problems remembering and predict IUPAC word-root during IUPAC nomenclature of higher alkanes (C >11). Here in this innovative article, I have tried to focus IUPAC nomenclature of higher alkanes (11C to 90C) through the prediction of IUPAC word root by using innovative mnemonics to make the concept unambiguous, simpler, time economic, and interesting. http://pubs.sciepub.com/wjce/9/2/1/wjce-9-2-1.pdf hydrocarbon word-root initial number natural number even number odd number convenient prefixes convenient format
