← ScienceWhich consequence results when ethylene's double bond breaks?
A)Polymer chain propagation occurs✓
B)Catalyst site deactivation happens
C)Aromatic ring resonance increases
D)Gas density dramatically decreases
💡 Explanation
Polymerization happens because the breaking of ethylene's double bond forms reactive sites, enabling radical chain propagation. This is how polyethylene forms, rather than deactivation or resonance, due to the radical mechanism.
