← ScienceWhich risk increases when an alkene molecule photodissociates?
A)Increased radical chain polymerisation occurrence✓
B)Accelerated electrophilic addition reactions
C)Favored unimolecular nucleophilic substitution
D)Enhanced molecule elimination pathway acidity
💡 Explanation
Photodissociation creates free radicals because homolytic bond cleavage dominates when molecules absorb high energy photons; therefore, radicalisation occurs, and it increases polymerisation events rather than changing ionic reaction priorities.
