← ScienceWhich phenomenon causes a blacksmith's quench oil to slowly degrade at elevated temperatures?
A)Homolytic cleavage creates free radicals✓
B)Increased hydrogen bonding dominates viscosity
C)Polymer entanglement lowers flash point
D)Esterification forms polymeric waxes
💡 Explanation
Homolytic cleavage creates free radicals in hydrocarbons, causing oxidation and polymerization of the oil because increased thermal energy promotes bond breakage. Therefore, the oil degrades due to chain reactions rather than viscosity changes alone.
