Question

Which of the following statements is correct regarding LDP and HDP?

(a) Both have different monomers

(b) Both have same structures

(c) Both have similar preparation conditions

(d) Both are chemically inert

The question was posed to me in an interview.

I need to ask this question from Types of Polymerisation Reactions in chapter Polymers of Chemistry – Class 12

Answer 1

Correct choice is (d) Both are chemically inert

To explain I would say: Low-density and high-density polythene have the same monomeric unit, ethene. Both are synthesized under very different pressure and temperatures conditions. LDP has a branches whereas HDP is a linear structure. Both are chemically inert and tough.
