What is the EN value of iodine?

2.66
The first scale of electronegativity was developed by Linus Pauling and on his scale iodine has a value of 2.66 on a scale running from from about 0.7 (an estimate for francium) to 2.20 (for hydrogen) to 3.98 (fluorine).

What does a high iodine number mean?

The more iodine is attached, the higher is the iodine value, and the more reactive, less stable, softer, and more susceptible to oxidation and rancidification is the oil, fat, or wax.

How does unsaturation measures value of iodine?

The iodine value of an oil is the number of grams of iodine absorbed by 100g of oil; since iodine adds across double bonds this is a measure of the unsaturation present.

What is 12.69 in iodine value formula?

Determination of iodine value The iodine value was determined by the PORIM Test Method8. Iodine value was calculated as 12.69N (V2 – V1)/W where N=Normality of Na2 S2 O3 used; W=the Volume in millilitres of Na2S2O3 used (Blank); V1=the Volume in millilitres of Na2S2O3 solution used for the determination (test sample).

How is iodine value calculated?

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).

Which lipid would you expect to have the highest iodine number?

Thus, the higher the iodine value, the more unsaturations are present in the fat. 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.

Which oil has the highest iodine value?

Thus, the higher the iodine value, the more unsaturations are present in the fat….Iodine values of various oils and fats.

Fat	Iodine value (gI/ 100g)
Rapeseed oil	94 – 120
Rice bran oil	99 – 108
Safflower oil	135 – 150
Sesame oil	100 – 120

Does olive oil contain iodine?

Sunflower oil, about 70% PUFA, has a high iodine number, and olive oil, rich in the mona- unsaturated oleic acid, has a moderately high iodine number.

Is iodine value good or bad?

Deterioration in the vegetable oils is reflected by the decrease in iodine value. Iodine value is used to measure unsaturation or the average number of double bonds in fats and oils. A high, iodine value indicates high unsaturation.

What increases with increase in iodine value?

Increased iodine value (increasing unsaturation) of fats increased apparent fatty acid digestibility, especially as iodine value increased from 11 to 27.
