Zorluk: OrtaSynthetic Polymers, Carbohydrates, Amino Acids, and Proteins

Match each synthetic polymer or biomolecule listed in Column A with its corresponding chemical linkage and structural classification in Column B.

  • Nylon-6,6Polyamide linkage formed by condensation polymerization of hexanedioic acid and hexane-1,6-diamine
  • Terylene (Dacron)Polyester linkage formed by condensation polymerization of benzene-1,4-dicarboxylic acid and ethane-1,2-diol
  • StarchGlycosidic linkage formed by condensation polymerization of α\alpha-D-glucose monomers
  • ProteinPeptide (amide) linkage formed by condensation polymerization of α\alpha-amino acid monomers

Cevap

Nylon-6,6 pairs with polyamide linkage formed from hexanedioic acid and hexane-1,6-diamine; Terylene pairs with polyester linkage formed from benzene-1,4-dicarboxylic acid and ethane-1,2-diol; Starch pairs with glycosidic linkage formed from α\alpha-D-glucose monomers; Protein pairs with peptide linkage formed from α\alpha-amino acid monomers.
Each polymer is correctly matched to its functional linkage and monomer constituents: Nylon-6,6 is a polyamide formed from hexanedioic acid and hexane-1,6-diamine; Terylene is a polyester formed from benzene-1,4-dicarboxylic acid and ethane-1,2-diol; Starch is a polysaccharide held together by glycosidic linkages between glucose units; Protein is a natural polymer made of amino acids linked by peptide bonds.

Adım Adım Çözüm

1
Identify the monomer composition and functional groups of Nylon-6,6
Nylon-6,6 contains amide linkages formed between carboxylic acid (−COOH-\text{COOH}) groups of hexanedioic acid and amino (−NH2-\text{NH}_2) groups of hexane-1,6-diamine.
Synthetic polyamides require a di-acid and a di-amine reactant.
2
Identify the monomer composition and functional groups of Terylene
Terylene contains ester linkages (−COO−-\text{COO}-) formed between benzene-1,4-dicarboxylic acid and ethane-1,2-diol.
Polyesters are produced by reacting a dicarboxylic acid with a dihydric alcohol (diol).
3
Determine the structural linkages present in Starch
Starch is a polysaccharide composed of α\alpha-D-glucose monomers linked via condensation through glycosidic bonds.
Carbohydrates form ether-like condensation links known as glycosidic linkages.
4
Determine the structural linkages present in Proteins
Proteins are natural polymers made of α\alpha-amino acids joined together by peptide linkages (−CO−NH−-\text{CO}-\text{NH}-).
The reaction between the carboxyl group of one amino acid and the amino group of another forms a peptide bond.
