(a)
To determine: The carbon-skeleton of all the trimers that is formed from putrescine, adipic acid and terephthalic acid.
Interpretation: The carbon-skeleton of all the trimers that is formed from putrescine, adipic acid and terephthalic acid is to be drawn.
Concept introduction: The repeated bonding of monomer units lead to the formation of
(b)
To determine: The mole ratio of the three reactants.
Interpretation: The mole ratio of the three reactants is to be stated.
Concept introduction: The repeated bonding of monomer units lead to the formation of polymer. They are mainly synthesized through condensation or addition reaction of monomer units.
