Question

When glycerol is treated with excess of HI, it produces

• A. 2-iodopropane
• B. Allyl iodide
• C. Propene
• D. Glycerol triiodide

Hint:

In halogenation reactions, iodine often replaces the hydroxyl group in alcohols, leading to halogenated products.

Answer 1

The Correct Option is B

When glycerol reacts with excess iodine and heat, it undergoes substitution to form allyl iodide. The reaction involves the substitution of the hydroxyl group with an iodine atom.

Step 2: Conclusion.
The product of the reaction is allyl iodide, corresponding to option (b).
