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.

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.

These are in the wrong boxes. Why does the one on the left have a lower molar mass than the one on the right?
SYNTHESIS REACTIONS. For the following reactions, synthesize the given products from the given reactants.
Multiple reactions/steps will be needed. For the one of the steps (ie reactions) in each synthesis, write out the
mechanism for that reaction and draw an energy diagram showing the correct number of hills and valleys for
