a)
Interpretation: The monomers of Kevlar with the structure of Nomex polymer are to be drawn and the differences in their structures are to be stated.
Concept introduction: Polymer is defined as a substance made up of large number of units bonded together. A single unit is known as monomer.
To determine: The monomers of Kevlar polymer.
(b)
Interpretation: The monomers of Kevlar with the structure of Nomex polymer are to be drawn and the differences in their structures are to be stated.
Concept introduction: Polymer is defined as a substance made up of large number of units bonded together. A single unit is known as monomer. Polymers are formed mainly by two types of reactions namely, addition reactions and condensation polymerization reactions. The condensation polymerization reactions are defined as the reaction in which two or more monomers combine together to form a single molecule with an elimination of small molecules like water.
To determine: The structure of Nomex polymer and the differences in the structures of Kevlar and Nomex polymer.

- PLEASE READ!!! I DONT WANT EXAMPLES, I DONT WANT WORDS OR PARAGRAPHS FOR THE MECHANISM!!! THANKS First image: QUESTION 6. I have to show, with ARROWS and STRUCTURES, the mechanism of the reaction at the bottom. Also I have to show by mecanism why the reaction wouldn't work if the alcohol was primary. I also tried to draw the mechanism, tell me what to change. Please note that its an AMIDE thats formed not an AMINE the nitrogen has ONE hydrogen and one Phenyl-C-Phenyl. I already asked for this mechanism and got as a final product ...-NH2 not whats shown on the picture, thank you Ths second part. QUESTION 3. I just need a way to synthesize the lactone A, I already started please continue from where I left it Second image: I simply need the products, substrates or reagents, thank youarrow_forwardIndicate how to prepare a 10% sodium hydroxide (NaOH) solution to a slightly alkaline pH.arrow_forwardCH, CH CH₂ CH₂ Phytyl side chain 5.
