Which one of the following statements is true?

Options

  1. ASaponification of oil yields a diol
  2. BDrying of oil involves hydrolysis
  3. CAddition of antioxidant to oil minimizes rancidity
  4. DRefining of oil involves hydrogenation

Correct answer

C. Addition of antioxidant to oil minimizes rancidity

Step-by-step solution

Saponification of oils yields a triol (glycerol). Drying (hardening) of oil involves hydrogenation. Refining of oil is done by distillation or other such processes but not by hydrogenation. Antioxidants are added to prevent the oxidation of oil, thus they minimizes rancidity.
