MCQ
In the given reaction 

$\begin{array}{*{20}{c}}
  {O\,\,\,\,\,\,\,\,\,} \\ 
  {||\,\,\,\,\,\,\,\,\,\,} \\ 
  {C{H_3} - C{H_2} - C - C{H_2}COO{C_2}{H_5}} 
\end{array}\xrightarrow{{[X]\,}}(A)$$ \mathop {\xrightarrow{{(i)\,LiAl{H_4}\,}}}\limits_{(ii)\,{H_2}O/{H^ \oplus }} \begin{array}{*{20}{c}}
  {O\,\,\,\,\,\,\,\,\,} \\ 
  {||\,\,\,\,\,\,\,\,\,\,} \\ 
  {C{H_3} - C{H_2} - C - C{H_2} - C{H_2}OH} 
\end{array} + \,{C_2}{H_5}OH$

$[X]$ will be :

  • A
    $HCHO$
  • $\begin{array}{*{20}{c}}
      {C{H_2} - OH} \\ 
      {|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
      {C{H_2} - OH} 
    \end{array} + {H^ \oplus }$
  • C
    $\begin{array}{*{20}{c}}
      {C{H_2} - OH} \\ 
      {|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
      {C{H_2} - OH} 
    \end{array} + \mathop O\limits^ \ominus  H$
  • D
    $HCN$

Answer

Correct option: B.
$\begin{array}{*{20}{c}}
  {C{H_2} - OH} \\ 
  {|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
  {C{H_2} - OH} 
\end{array} + {H^ \oplus }$
