Question

*The colour of iodine disappeares in the reaction between an oil and iodine, however, there is no colour change with vanaspati ghee. What inference will you draw from this?*

1️⃣ There is single bond in molecules of oil.
2️⃣ vanaspati ghee is saturated.
3️⃣ molecules of oil contain saturated carbon chain.
4️⃣ there are double bonds in molecules of vanaspati ghee.​

Answer 1

Answer:

2nd option is correct

Vanapati ghee is saturated

Answer 2

The inference that I drew is that Vanaspati ghee is unsaturated.

• This test is known as the Huble's test which detects the saturated nature  of unsaturated nature of various oils and fats.
• When this test is conducted on oils with iodine that has mercuric chloride present in it, the color of iodine disappears but when the same test is performed with vanaspati ghee, the color does not fade away due to its saturated nature.
