The alkanes are oily and do not dissolve or mix with water, alkanes with 1-4 carbon atoms
are gases at room temperature, those with 4-17 carbon atoms are liquids at room
temperature, and those with more than 17 carbon atoms are solid at room temp.
Liquid alkanes with longer molecules are sticky liquids. There viscosity makes them suitable
as ingredients as lubricants.
All alkanes burn and do not react with acids or alkalis.
