Polymers that can conduct electricity are called conducting polymers. Some polymers can be made semiconducting; others can benearly metallic. Polyacetylene is an example of a polymer that is a semiconductor. It can also be doped to increase its conductivity.Polyacetylene is made from acetylene in a reaction that looks simple but is actually tricky to do:H—C≡ C— HAcetylene [— CH=CH— ]n Polyacetylene(a) What is the hybridization of the carbon atoms, and the geometry around those atoms, in acetylene and in polyacetylene?(b) Write a balanced equation to make polyacetylene from acetylene.

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
