MCQ
In the given reaction

$X + Y\mathop {\xrightarrow{{NaOH}}}\limits_{5\,^oC} \begin{array}{*{20}{c}}
  {OH\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
  {|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
  {C{H_3} - CH - CH - CHO} \\ 
  {\,\,\,\,\,\,\,\,\,|} \\ 
  {\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,C{H_3}} 
\end{array}$

$(X)$ and $(Y)$ will respectively be :

  • A
    $CH_3-CH_2-CHO$ and $CH_3-CH_2-CHO$
  • $CH_3-CHO$ and $CH_3-CH_2-CHO$
  • C
    $CH_3-CHO$ and $CH_3-CHO$
  • D
    $CH_3-CHO$ and $\begin{array}{*{20}{c}}
     \,\,\,\,\, {C{H_3}} \\ 
      |\,\, \\ 
      {C{H_3} - C - CHO} \\ 
      |\,\, \\ 
      \,\,\,\,\,{C{H_3}} 
    \end{array}$
