A. Draw the molecular structure of three monomeric units of the addition polymer that results from polymerization of acetylene. Only show the structure that would be found inside the brackets of a condensed formula for this polymer. It is understood that the terminal carbons connect to additional monomeric units in the polymer.
B.There are two possible geometirc isomers of plyacetylene. Identify the two isomeric forms.
