Answer
Low-density poly(ethene) (LDPE) consists of heavily branched carbon chains. The extensive branching in its molecular structure results in a lower density and less crystalline nature, which contributes to its flexibility and ductility.
Step 2
HDPE or high-density poly(ethene)

Answer
High-density poly(ethene) (HDPE), on the other hand, has a more linear structure with minimal branching. This structure leads to a higher density and more crystalline arrangement, enhancing its strength and rigidity compared to LDPE.
