During the industrial synthesis of a synthetic fiber, hexanedioic acid reacts with hexane-1,6-diamine with the elimination of water molecules to form amide linkages. Which polymer is formed from this process?

  1. Nylon-6,6Cevap
  2. B
    Terylene
  3. C
    Polyethene
  4. D
    Poly(methyl methacrylate)

Cevap

Nylon-6,6 is the polyamide formed by the condensation polymerization of hexanedioic acid and hexane-1,6-diamine.
The reaction between a dicarboxylic acid containing 6 carbon atoms (hexanedioic acid) and a diamine containing 6 carbon atoms (hexane-1,6-diamine) yields a synthetic polyamide known as Nylon-6,6 via condensation polymerization with the elimination of water.

Adım Adım Çözüm

1
Identify the functional groups of the monomers provided in the prompt.
Hexanedioic acid contains dicarboxylic acid groups (−COOH-COOH) and hexane-1,6-diamine contains diamine groups (−NH2-NH_2).
The reaction between carboxylic acid and amine functional groups forms peptide/amide bonds (−CONH−-CONH-).
2
Determine the type of polymerization and the resulting macromolecule class.
The reaction involves the loss of water molecules, which defines condensation polymerization forming a polyamide.
Condensation polymerization links bifunctional monomers together with the elimination of small molecules such as H2OH_2O.
3
Match the specific monomers to the corresponding polymer name.
Hexanedioic acid (6 carbon atoms) and hexane-1,6-diamine (6 carbon atoms) produce Nylon-6,6.
The numbers '6,6' in Nylon-6,6 indicate that both the diamine and dicarboxylic acid monomers contain 6 carbon atoms each.
