Question

1. Which of the following has high density
(a) Linear polymer
(b) cross linked polymer
(c) Branched polymer
(d) none of the above​

Answer 1

Explanation:

cross linked polymer, if it is correct plz mark me as brainlist and follow me , have a nice day ☺

Answer 2

The correct solution to the given question is option a: Linear polymer.

• The high density of polymers means that there is very least space present between the units of polymers and mass is very high in a given volume.
• Linear polymers have a density very high because they are arranged in a way of chain that is straight where the monomeric units are closely bonded to each other and therefore packed very tighly.
• This tight packing leads to its high density.
• Branched polymers have low density because there is a lot of space between units and intermolecular therefore they soften very easily.
• The cross-linked polymer has strong links between units in the molecule however there packing structure of the molecule do have spaces between them having lesser density compared to linear polymers.
• Hence, the linear polymer is the correct answer.
