Vedclass · Answer

(B) Glycerol reacts with $P_4 + I_2$ (which generates $PI_3$ in situ) to initially form $1,2,3-triiodopropane$. This intermediate is unstable due to the presence of iodine atoms on adjacent carbons and undergoes elimination of $I_2$ to form allyl iodide $(CH_2=CH-CH_2I)$. $CH_2OH-CHOH-CH_2OH$ $\xrightarrow{P_4/I_2} [CH_2I-CHI-CH_2I]$ $\xrightarrow{-I_2} CH_2=CH-CH_2I$
