The polymerization of chloroethylene, CH 2CHCl, takes place by the splitting of
one of the bonds of the double bond to form a highly reactive carbon containing
a single electron at either end of the molecule.

The electron then pairs with another electron on a different molecule, forming
a chain.

21-5 Proteins
Proteins are naturally occurring organic polymers that are composed of
monomer units called amino acids. Amino acids contain a carbon atom with
two functional groups, an amino group, ([NH 2), and a carboxylic acid group,
([COOH) attached. This central carbon atom also has a hydrogen atom and
another organic group, an “R” group, attached. The identity of the R group
determines the identity of the amino acid.
