The structure of repeating monomer unit in the polyester formed by the condensation of oxalic acid and 1, 3 - propanediol is to be stated. Concept introduction: The reaction between acid and alcohol gives an ester as a major product. The ester group is derived by a carboxylic acid group in which the acidic hydrogen is replaced by an alkyl group. Esters are identified for their characteristic sweet smells.

Answer 1

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.
