2: Polymer Chains

If two of the hydrogen atoms are removed and the carbon atom decides to bond with two other carbon atoms then it can be seen how long chains can be formed.

A carbon atom bonded to 2 hydrogen atoms can be considered a building block or unit of the polymeric chain. These units make up monomers, which are repeating units in the molecular chain structure.

A series of monomers bonded together to form a molecular chain is known as a polymer. The polymer shown is known as polyethylene.
