Unsaturated oils compared to saturated oils have___________________?
Correct answer: A. Lower melting point & higher reactivity to oxygen
- A. Lower melting point & higher reactivity to oxygen
- B. Higher melting point & higher reactivity to oxygen
- C. Lower melting point & lower reactivity to oxygen
- D. Higher melting point & lower reactivity to oxygen
Explanation
Double bonds in unsaturated oils lower the packing efficiency of their chains, reducing the melting point, and provide reactive sites for oxidation. Saturated oils therefore generally melt at higher temperatures and resist oxidation more strongly.
