Three repeating units of the addition polymer made from acetylene is to be determined. Concept Introduction: Polymers are materials made of long repeating chain of molecules called monomer units. Based on the modes of polymerization , polymers are classified as follows: Addition polymers – Addition polymers are formed by repeated addition of the monomer units. The monomer units are unsaturated hydrocarbons generally. There is no elimination of molecules in the reaction. Condensation polymers – Condensation polymers are formed by repeated condensation between two different monomer units along with the formation of elimination products like water.

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .
