← ScienceWhich outcome occurs when molecular orbitals hybridize during ethene polymerization?
A)Increased radical chain initiation rate
B)Enhanced material thermomechanical stability✓
C)Reduced monomer steric hindrance effects
D)Elevated ionic polymerization propagation efficiency
💡 Explanation
Enhanced material thermomechanical stability is achieved because sp3 hybridization leads to the formation of stronger sigma bonds rather than weaker pi bonds, and stiffer polymer chains; therefore the higher thermal stability, rather than faster reaction kinetics, results.
