Hint: To answer this question we have to know about iodine value of fat and oil. The iodine value of fat and oil is defined as the number of grams of iodine gas required to combine with grams of fat and oil.
Complete Step by Step Solution:
The iodine value of fat and oil is defined as the number of grams of iodine gas required to combine with a $100$ gram of fat and oil.
Thus the 'iodine value' of an oil or fat is measured in terms of weight of iodine gas. The iodine value determines the number of unsaturation present in the acid part of the fat or oil.
Thus we can write that the 'iodine value' of an oil or fat indicates the unsaturation present in acid contents of fat and oil.
Thus the correct option is C.
Additional information: An oil is a nonpolar substance. It is composed primarily of hydrocarbons. It can be both hydrophobic and lipophilic. Oils are usually flammable and surface active substances. Most of the oils are unsaturated lipids that are present as a liquid at room temperature. Fats have the same property as oil but it exists as a solid at room temperature. Both fat and oil are made of glycerol.
Note: The iodine value of oil and fat is determined using iodine gas. Iodine gas is a halogen. It is a violet colored gas.
