The one which has least iodine value is

A

ginger oil

B

ghee

C

groundnut oil

D

sunflower oil

Text Solution

Verified by Experts

The correct Answer is:
B

The degree of unsaturation of a fat or oil is measured by its iodine number which is defined as the number of grams of iodine what would add to carbon carbon double bonds (C=C) present in 100 grams of the far or oil. Hence, greater the number of doubel bonds in the acid residues of a trglyceride, greatger will be the iodine number. Because a satuarated fatty acid has no double bonds, it takes up no iodine, this its iodine number is zero.
Among the given options, ghee has the least iodine value as it is saturated whereas the other compounds conain some degree of unsaturation.
