The structure of polyurethane formed by the copolymerization of a diol with a diisocyanate is to be drawn. Concept introduction: The polymers (repeating structural units) are derived from the simple and reactive molecules, called as monomers. Depending upon the mode of polymerization , polymerization mainly occurs by addition and condensation polymerization reactions. Copolymerization reactions are defined as the reactions of two different monomers forming a copolymer . Polyurethane is formed by the copolymerization of diol with diisocyanate. To determine: The structure of polyurethane formed by the copolymerization of a diol with a diisocyanate.

Question

a) Write out 6 completely different reactions of acetophenone (reagent, product). b) Write out 3 preparations of 1-methylcyclohexanol, using a different starting material for each one. You may use preps where you just change the functional group, and/or preps where you construct the carbon chain. c) Write out 3 preparations of 2-ethoxybenzoic acid, a different starting material for each one. You may use preps where you just change the functional group, and/or preps where you construct the carbon chain.

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.
