Explain the terms polymer and monomer.

Explanation

Polymers are high molecular mass substances consisting of a very large number of simple repeating structural units joined together through covalent bonds in a regular fashion. Polymers are also called macromolecules. Some examples are polythene, nylon-66, bakelite, rubber etc. Monomers are the simple and reactive molecules from which the polymers are prepared either by addition or condensation polymersation. Some examples are ethane, vinyl chloride, acrylonitrile, phenol and formaldehyde etc.
