← ScienceWhich outcome occurs when ethylene molecules undergo polymerization?
A)Formation of long-chain polyethylene✓
B)Cleavage of all carbon-carbon bonds
C)Production of branched hydrocarbon chains
D)Precipitation of gaseous carbon dioxide
💡 Explanation
Polymerization involves addition reactions forming macromolecules. The **addition polymerization** mechanism causes ethylene monomers to bond end to end, forming a polymer, because electrons in pi bonds reshuffle to sigma bonds, therefore a long chain forms rather than carbon cleavage alone.
