Accepted Answer

${\rm{C}}{{\rm{H}}_3}{\rm{C}}{{\rm{H}}_2}{\rm{C}}{{\rm{H}}_2}{\rm{I}}\xrightarrow{{{\rm{HI}}/\Delta\; 150^\circ C}}$

Answer

${\rm{C}}{{\rm{H}}_3}{\rm{CH}} = {\rm{C}}{{\rm{H}}_2}\xrightarrow[{2.{\rm{AgN}}{{\rm{O}}_3}/{\rm{NaOH}}}]{{1.{{\rm{B}}_2}{{\rm{H}}_6}}}$

Answer

${\rm{C}}{{\rm{H}}_3}{\rm{C}}{{\rm{H}}_2}{\rm{C}}{{\rm{H}}_2}{\rm{Cl}}\xrightarrow[{2.{{\rm{H}}_2}{{\rm{O}}_2}}]{{1.{\rm{Mg}}/{\rm{ether}}}}$

Answer

${\rm{C}}{{\rm{H}}_3}{\rm{C}}{{\rm{H}}_2}{\rm{C}}{{\rm{H}}_2}{\rm{COONa}}\xrightarrow[\Delta ]{{{\rm{NaOH}}({\rm{CuO)}}}}$
