Chemical Properties of Three Functional Groups Alkane Commonly referred to as hydrocarbons, alkanes only contain single bonds linking each carbon and hydrogen atom together. In general, alkanes are reactive with other atoms and molecules. One chemical property of an alkane molecule is its ability to ...
