Question:
Identify the monomers used to prepare polycarbonate.
Identify the monomers used to prepare polycarbonate.
Show Hint
Polycarbonate is a condensation polymer of a bisphenol and a carbonyl source.
Updated On: Nov 13, 2026
Butadiene and acrylonitrile
Urea and formaldehyde
Bisphenol and phosgene
Vinyl chloride and ethylene glycol
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Polycarbonates contain the carbonate linkage \(-\text{O}-\text{CO}-\text{O}-\).
Step 2: Monomers
They are prepared from bisphenol A and phosgene \((\text{COCl}_2)\), or diphenyl carbonate.
Step 3: Compare the options
Option (C): bisphenol and phosgene.
Final Answer:
Polycarbonate is made from bisphenol and phosgene. \[ \boxed{\text{(C) }\text{Bisphenol and phosgene}} \]
