← ScienceWhich molecular consequence arises in Teflon during high-energy electron irradiation?
A)Carbon-carbon bond chain scission✓
B)Increased van der Waals forces
C)Fluorine substitution by hydrogen
D)Crystallinity index number increases
💡 Explanation
Chain scission, a form of radioactive decay, induces bond breakage because incident electrons transfer surplus energy to the bonds, weakening links; therefore the polymer degrades, which is chain scission occurring, rather than changing intermolecular forces or elemental composition.
