Chapter 20, Problem 67PP

Interpretation Introduction

Interpretation:

The starting monomers should be drawn and identified for the given set of target (polymer) molecules.

Concept introduction:

Electrophile: An electrophile is a species that accepts a pair of electrons to form a new covalent bond.

Nucleophilic reaction: electron rich nucleophiles attacks the positive or partially positive charge of an atom and replaces a leaving group is called Nucleophilic Substitution reaction.

Condensation reaction:  The several organic reactions that proceeds in a step-wise reaction to produce the addition product. This type of reaction involves the formation of ammonia, ethanol or mineral acids; it is a versatile class of reaction that can occur in acidic or basic conditions or in the presence of catalyst.

Addition Reaction: It is defined as chemical reaction in which two given molecules combines and forms product. The types of addition reactions are electrophilic addition, nucleophilic addition, free radical additions and cycloadditions. Generally, compounds with carbon-hetero atom bonds favors addition reaction.

Elimination Reaction: It is just reverse reaction of addition where substituent from the given molecule is removed via $E1$(the reaction depends only on the substrate involved in the reaction) or $E2$(the reaction depends on both of the substituents in the reaction) mechanism.
