Alkane, an Uncommon card

The card carries these facts from its Wikipedia article.

• In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single.
• Alkanes have the general chemical formula CnH2n+2 and therefore range in complexity from the simplest case of methane, where n = 1, to arbitrarily large and complex molecules, like hexacontane or 4-methyl-5- octane, an isomer of dodecane.
• The International Union of Pure and Applied Chemistry defines alkanes as "acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2, and therefore consisting entirely of hydrogen atoms and saturated carbon atoms".
