Answer:
Correct Answer: B
Solution:
$ \underset{Glycerol}{\mathop{\underset{CH_2OH}{\overset{CH_2OH}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}HOH\ }}}}}+3HI\xrightarrow[-3H_2O]{}[ \underset{CH_2-I}{\overset{CH_2-I}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}H-I}}} ]\xrightarrow[-I_2]{}\underset{\text{Allyl iodide}}{\mathop{\underset{CH_2\ }{\overset{CH_2I}{\mathop{\underset{||}{\overset{|}{\mathop{C}}}H\ \ }}}}} $
