Crude Oil, Hydrocarbons and Alkanes
-
Crude Oil
Finite resource found in the Earth's crust. It is the remains of organisms that lived a died millions of years ago - mainly plankton which was buried in mud.
-
Crude oil is a complex mixture of hydrocarbons. The carbon atoms in these molecules are joined together in chains and rings. In the ball and stick model, carbon atoms are black and hydrogen atoms are white
-
-
Alkanes
The alkanes form a homologous series. Like all homologous series, the alkanes:
-
-
Show a gradual variation in physical properties, such as their boiling points
-
-
The ball and stick model on the right show that the covalent bonds are not really at angles of 90 degrees, as shown in the structures.
-
Fractional Distillation is used to separate crude oil into simpler, more useful mixtures. This method can be used because different hydrocarbons have different boiling points.
