The structures of linear chain polymer and branched chain polymer obtained from the condensation of phenol and formaldehyde in 1:2 ratio needs to be determined. Concept Introduction: A polymer is a long chain consists of large number of monomer units. The monomers are repeated units in a polymer they are linked to each other in different orders to produce different polymers . These monomer units are linked to each other either through the formation of peptide linkage or glycosidic linkage or by removal of any moiety such as a water molecule. Polyvinyl chloride, bakelite, polystyrene are some of the example of polymers.

Answer 1

Question

Definition Definition Monomer units that are not only combined in the linear chain but are also attached through branches of different lengths along the main chain. Branched-chain polymers have a lower density, lower melting point, and lower tensile strength compared to linear chain polymers because branched-chain does not pack well. Examples of branched-chain polymers are amylopectin and glycogen.
