A Polymer

“A polymer is a substance which has a molecular structure comprising of a large
number of identical molecules covalently bonded together to form a long chain
structure. Many synthetic organic materials are polymers, such as nylon, polythene
and Kevlar.”
The extract mentions ‘covalent bonds’. Explain what these are, and the formation of
different types that can exist i.e. single, multiple etc.
Do some research and identify 4 simply covalently bonded molecules. Draw dot and
cross diagrams of each to show the bond formation of each of your 4 examples.
