The reaction mechanism may be classified into two categories:
Chain growth polymerization:
Chain growth polymers are produced by chain growth polymerization or addition polymerization. In this process an initiator is added to the reaction mixture. This initiator gets added to the carbon-carbon double bond and yields a reactive monomer (intermediate). This reactive intermediate reacts with the monomer and this process keeps on repeating to give rise to final polymeric product.
Step growth polymerization:
Step growth polymers are produced by step growth polymerization or condensation polymerization. In this process, each bond is formed in a step wise manner. In this the product of each is again a bi-

Interpretation:
Draw the structures of the polymers formed by the given monomer units.
Concept introduction:
The term “polymer” is derived from the two words poly+mer. Where poly means ‘many’ and mer means ‘unit’, when combined known as polymer. The polymerization is the process of reacting monomer molecules together in a chemical reaction to give rise to a polymer. If the reacting units are same then this type of polymer is known as homopolymer and if the reaction takes place between different molecules then it is called copolymer.

Step growth polymerization:
Step growth polymers are produced by step growth polymerization or condensation polymerization. In this process, each bond is formed in a step wise manner. In this the product of each is again a bi-functional group and the condensation goes on.

- Draw the arrow pushing reaction mechanism. DO NOT ANSWER IF YOU WONT DRAW IT. Do not use chat gpt.arrow_forwardComplete the following esterification reaction by drawing the structural formula of the product formed. HOH HO i catalyst catalyst OH HO (product has rum flavor) (product has orange flavor)arrow_forwardThe statements in the tables below are about two different chemical equilibria. The symbols have their usual meaning, for example AG stands for the standard Gibbs free energy of reaction and K stands for the equilibrium constant. In each table, there may be one statement that is faise because it contradicts the other three statements. If you find a false statement, check the box next to t Otherwise, check the "no false statements" box under the table. statement false? AG"1 no false statements: statement false?

- Complete the following esterification reactions by drawing the line formulas of the carboxylic acid and alcohol required to form the ester shown. catalyst catalyst catalyst apricot fragrancearrow_forwardShow the saponification products of the following ester: You don't need to draw in the Na+ cation. catalyst, A catalyst, A catalyst, Aarrow_forwardWhat would happen if the carboxylic acid and alcohol groups were on the same molecule? In essence, the molecule reacts with itself. Draw the structure of the products formed in this manner using the reactants below. If two functional groups interact with one another on the same molecule, this is called an “intramolecular" (within one) rather than "intermolecular" (between two or more) attack.
