Vedclass · Answer

(B) When glycerol $(CH_2OH-CHOH-CH_2OH)$ is heated with excess $HI$,the $-OH$ groups are first replaced by iodine atoms to form $1,2,3-$tri-iodopropane.This intermediate is unstable and undergoes elimination to form allyl iodide $(CH_2=CH-CH_2I)$.Finally,the allyl iodide reacts with $HI$ to form isopropyl iodide $(CH_3-CHI-CH_3)$ as the stable final product.

On heating glycerol with excess amount of $HI$,the product formed is -
