Terylene, a polyester, is formed by the condensation of
- A. two amino acids
- B. a diol with a dicarboxylic acid
- C. two molecules of ethene
- D. glucose units
Explanation
Ethane-1,2-diol reacts with benzene-1,4-dicarboxylic acid so that ester linkages form and water is eliminated, giving a polymer used for clothing fibre and drink bottles. A diamine with a diacid would give a polyamide such as nylon instead. Each monomer must be difunctional for a chain rather than a single small molecule to result.
