Question

Glycerol on heating with excess moles of HI produce
(a) 1,2,3-tri Iodopropane (b) allyl iodide
(c) Isopropyl iodide (d) propane

Answer 1

Glycerol is a trihydric alcohol whose IUPAC name is propane-1, 2, 3-triol and in industry it is known as glycerine.When glycerol is heated with excess of HI,the allyl iodide formed first is reduced to propene.Propene in presence of excess of HI forms iso-propyl iodide.Hence option C is correct.
