英语翻译A consistent reaction,besides combustion,that aikanes undergo is free radical halogenation.IN this process,hydrogens on alkyl groups are replaced by halogens(molecules like chlorine and bromine on the periodic tablle).A typical reaction is demonstrated usingpropane.Methane is the simplest hydrocarbon consisting of a colorless,odorless gas at room temperature.THE odor in "natural gas"used in homes is actually added to methane for safety reasons.
