Question

Which of the following polymers has a structure as shown?

• A. High-density polythene
• B. Bakelite
• C. Low-density polythene
• D. Polyvinyl chloride

Answer 1

The correct option is C Low-density polythene

Explanation: The shown structure has unconnected linear chains with some intermediate branches. This is a branched chain polymer. They are irregularly packed and have lower density and strength than linear polymers.
Low density polythene is an example of branched chain polymer.

Polyvinyl chloride and High-density polythene are linear polymers.

Bakelite is a cross linked polymer

Hence, option (a) is correct.
