Is it possible to determine the number of double bonds if iodine number is given
Answers
Answer:
The iodine value (or iodine adsorption value or iodine number or iodine index, commonly abbreviated as IV) in chemistry is the mass of iodine in grams that is consumed by 100 grams of a chemical substance. Iodine numbers are often used to determine the amount of unsaturation in fats, oils and waxes. In fatty acids, unsaturation occurs mainly as double bonds which are very reactive towards halogens, the iodine in this case. Thus, the higher the iodine value, the more unsaturations are present in the fat.[1] It can be seen from the table that coconut oil is very saturated, which means it is good for making soap. On the other hand, linseed oil is highly unsaturated, which makes it a drying oil, well suited for making oil paints
Explanation:
Iodine values are most commonly calculated using a regression equation based on fatty acid concentrations: iodine value (IV)=16:1 (0.95)+18:1 (0.86)+18:2 (1.732)+18:3 (2.616)+20:1 (0.785)+22:1 (0.723).
