When glycerol is treated with excess of HI, it produces:

1. glycerol triiodide
2. 2–iodopropane
3. allyl iodide
4. propene

Correct answer: 2–iodopropane

Solution

When glycerol reacts with excess HI, it undergoes a series of substitution reactions where hydroxyl groups are replaced by iodine, ultimately forming 2-iodopropane as the major product.
