(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.

Draw the structure of the strongest acid in the table above. B. Explain why cyanoacetic acid and methoxyacetic acid are more acidic than their correspondingly substituted benzoic acid counterparts.arrow_forwardDraw the curved arrow mechanism for this reaction starting with 2-propanol in sulfuric acid. Show all nonzero formal charges and all nonbonded electrons in each step. Species not involved in a particular step do not need to be included in that step, and resonance forms do not need to be shown. Note that the alcohol is in much higher concentration than H₂O in this reaction. Harrow_forwardProvide reactions showing the following conversions: * see imagearrow_forward
