The monomers from the following step-growth condensation polymer are to be identified. Concept introduction: Polymers are the macromolecules that are formed by the repeating monomeric units. Step-growth condensation polymers are synthesized by the stepwise reaction of monomers. The monomers contain bifunctional or multifunctional groups. In step-growth polymerization , small molecules such as water, ammonia are eliminated. The condensation reaction of the dicarboxylic acid and diamine are employed for the synthesis of polyamide. Ammonia molecule is eliminated and amide linkage is formed. The general reaction for the synthesis of two repeating units of the polymer is, Here, R is an alkyl group.

A certain half-reaction has a standard reduction potential Ered +1.26 V. An engineer proposes using this half-reaction at the anode of a galvanic cell that must provide at least 1.10 V of electrical power. The cell will operate under standard conditions. Note for advanced students: assume the engineer requires this half-reaction to happen at the anode of the cell. Is there a minimum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the minimum. Round your answer to 2 decimal places. If there is no lower limit, check the "no" box.. Is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the maximum.
