Which consequence results when alkane polymers degrade under ultraviolet exposure?

A)Chain scission reduces average molecule size
B)Increased crosslinking increases material hardness
C)Crystallinity decreases increasing transparency
D)Hydrogen bonding increases tensile strength

💡 Explanation

Ultraviolet exposure causes homolytic cleavage of C-C bonds through chain scission; free radicals initiate further depolymerization because this destabilizes the main chain, resulting in random breaking rather than increased crosslinking at the same temperature.
