Q. Statement 1 : When glycerol is heated with hydrogen iodide, only allyl iodide is formed
Statement 2 : With hydrogen iodide, glycerol forms three different compounds like propene, isopropyl iodide and allyl iodide

Alcohols Phenols and Ethers

Solution:

When glycerol is heated with a small amount of $HI$, allyl iodide is fromed

When glycerol is heated with a large amount of $HI$, the allyl iodide first formed is reduced to propene, which in presence of excess of HI forms isopropyl iodide
