The step-growth polymer nylon 6 is prepared from caprolactam. The reaction involves initial reaction of caprolactam with water to give an intermediate open-chain amino acid, followed by heating to form the polymer. Propose mechanisms for both steps, and show the structure of nylon 6. Concept introduction: This step growth polymerization thus begins with a single functional monomer that has two different functional groups , NH 2 AND CoaH.

Question

Carototoxin is a natural pesticide produced by carrots, with formula C₁H2O. It undergoes hydrogenation with Pd to: give product A, C,H,O, and with Lindlar's catalyst to give product B, C,H2O. Ozonolysis followed by zinc leads to a mixture of methanal, octanal, 1,2-ethanedioic acid, 3-oxopropanoic acid, and 2-hydroxy-3-oxopropanoic acid. Draw possible structures for carototoxin, A, and B. Product B structure H2, Lindlar's Structure of carototoxin H2, Pd/C Product A structure

Answer 1

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.

CH,OCH,CI SnCl, CH,CI The chloromethylated polystyrene resin used for Merrifield solid-phase peptide synthesis is prepared by treatment of polystyrene with chloromethylmethyl ether and a Lewis acid catalyst. The reaction involves the following steps: 1. Reaction of the ether with the Lewis acid to form cation 1; 2. Electrophilic aromatic substitution to form resonance stzbilized cation 2: 3. Deprotonation yields aromatic ether 3: 4. Protonation to žorm protonated ether 4; 5. Displacement by chloride ion to form the final product Write out the mechanism on a separate sheet of paper and then draw the structure of the resonance contributors of the resonance stabilized cation 2. • Use Rl groups to indicate the points where the polymer repeats. The R group tool is located in the charges and lone pairs drop-down menu. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. • Separate resonance structures using the symbol from the…
