MCQ
$C{H_3}C{H_2}C \equiv N\xrightarrow{X}C{H_3}C{H_2}CHO$ The compound $X$ is
  • $SnCl_2/HCl/H_2O$, boil
  • B
    $H_2/Pd -BaSO_4$
  • C
    $LiAlH_4$/ethe
  • D
    $NaBH_4/ ether / H_3O^+$

Answer

Correct option: A.
$SnCl_2/HCl/H_2O$, boil
a
Completing the given reaction

$C{{H}_{3}}-C{{H}_{2}}-C\equiv N$ $\xrightarrow{{SnC{l_2}\,/\,HCl}}$ $C{H_3}C{H_2}CH = NH$

$\xrightarrow[{(Ether)}]{{{H_2}O\,,\,boil}}$ $C{H_3}C{H_2}CHO\, + \,N{H_4}Cl$

It is stephen's reduction.
