Alkanes alkanes are saturated hydrocarbonsthey consist of the elements carbon and hydrogen, and all the bonds between the carbon atoms are single bondsthey have the general formula c n h 2n+2since all alkanes are similar in structure and properties, they are called a homologous series the structure of an alkane, as with all hydrocarbons, can be represented with a.
Alkanes contain only single bonds, which means they are saturated with hydrogen atoms they are the basic hydrocarbons and the starting points for understanding the chemistry of other, more complex molecules.
