← ScienceWhich outcome occurs when tensile stress initiates backbone unraveling in polyethylyne molecules?
A)Increased radical chain scission events✓
B)Crystallinity domains experience enhanced folding
C)Increased density dependent crosslinking
D)Van der Waals forces are amplified
💡 Explanation
Increased radical chain scission occurs through homolytic cleavage. The applied stress breaks the backbone covalent bonds initiating the **radical mechanism** because of the lowered activation energy required, therefore causing chain scission, rather than just bond stretching or overall fracture.
