View IR Reference Sheet from CHEM 2540 at Ohio State University. The monovalent radicals C n H 2n+2 derived from alkanes by loss of one hydrogen atom are called alkyl groups (methyl, ethyl, etc. Alkyl Halides . com Lab 5 - S N 2 Reactions of Alkyl Halides The rate of this reaction is directly proportional to the concentration of both methyl bromide and sodium hydroxide. Methyl is the only alkyl group derivable from methane and ethyl the only one from ethane. Carbon at position 6 appeared at 69. An alkene is added to the dish in the upper-left corner of the projector and an alkane is added to the dish in the upper-right corner. Naming alkanes with alkyl groups .
