Many of these molecules are used in the production of other materials, such as plastics, but their main use is as a fuel source. They are named under the systematic nomenclature scheme in the same way that alkenes are, except that instead of the name ending with the suffix –ene, the names of alkynes end with the suffix –yne. Alkenes and alkynes are named by identifying the longest chain that contains the double or triple bond. Alkanes are sp3 hybridized. 1 mole of CO2 Alkanes, such as butane and gasoline, also react easily in the presence of a spark or flame. Alkynes generally have slightly higher boiling points than alkenes. Carbon is special because it can form covalent bonds with itself. b. Alkane molecules have only single bonds between carbon atoms.
