← ScienceWhich consequence results when excessive mechanical stress induces bond scission?
A)Mechano-radicals form, initiating polymerization✓
B)Increased crystallinity enhances material rigidity
C)Enhanced cross-linking improves elasticity
D)Induced doping alters semiconductor properties
💡 Explanation
Mechanical stress breaks covalent bonds via homolytic cleavage, inducing radical formation, therefore forming mechano-radicals which can initiate uncontrolled polymerization reactions, rather than promoting crystallinity or cross-linking like other reactions under thermal conditions.
