Concept Introduction:
(f)
Answer to Problem ISP
The basic condition for condensation polymerization is that there should be two different functional groups present in the same monomer or in two different monomers. Since this basic condition or requirement is not fulfilled by the reactants of part (b). Thus, the formation of polymer cannot takes place.
Explanation of Solution
The formation of polymer between the two reactants cannot takes place as there is only one functional group present in their structural formula. The basic condition for condensation polymerization is that there should be two different functional groups present in the same monomer or in two different monomers. Since this basic condition or requirement is not fulfilled by the reactants of part (b).
Thus, the formation of polymer cannot takes place.
