Vedclass · Answer

(A) Drying oils are oils that transform into hard solids upon exposure to air and light,such as linseed oil.These oils contain a high proportion of unsaturated fatty acids,specifically linoleic acid $(C_{17}H_{31}COOH)$ and linolenic acid $(C_{17}H_{29}COOH)$.When exposed to oxygen and light,these unsaturated bonds undergo oxidative polymerization,leading to the formation of a tough,solid film.This property is widely utilized in the paint industry,where these oils serve as a vehicle or binder for paints.
