A new inquiry-based activity has been created for general, organic, and biological chemistry students that enables them to determine and practice using IUPAC alkane naming rules. Inquiry pedagogy was chosen so students could achieve deeper, longer-lasting learning than they might have achieved using standard lecture. Novel features include students creating their own memory devices for the prefixes meth- through dec-, creating and naming their own alkanes, and answering an application question based on research into autism. Students also determine that the prefixes refer to the number of carbon atoms, research the -ane suffix, draw the structures for homologous straight chain alkanes, learn parent/substituent terms and identification, determine the various rules for carbon numbering, research Greek prefixes, examine name syntax, and practice using the rules they’ve learned. Increased numbers of students answered test questions on alkane nomenclature correctly versus previous years’ tests. The activity will be presented.
