Q19 / 84 · NTA Abhyas (NEET) 2020 · Chemistry · Polymers

Terylene is a polymer obtained from

  • A
    Ethylene glycol and glycerol
  • B
    Ethylene glycol and glyceraldehydes
  • Correct answer
    C
    Ethylene glycol and terephthalic acid
  • D
    None of the above

Solution

Ethylene glycol on reaction with terephthalic acid forms the polymer terylene(also known as Dacron or terene) which is used as synthetic fibre.

nHOCH 2 · CH 2 OH + nHOOC · C 6 H 4 · COOH → - nH 2 O - OCH 2 - CH 2 - O - C O || - C 6 H 4 - C O || - n Ethylene glycol Terephthalic acid Polymer Terylene

Hence, the correct answer is option: 'C'.
