      {\,\,\,\,O\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
      {||\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
      {C{H_3} - C - O\,Na\xrightarrow{{{\text{Elec}}trolysis}}} 
    \end{array}$
  • C
    $\begin{array}{*{20}{c}}
      {\,\,O\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
      {||\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
      {C{H_3} - C - OH\xrightarrow[\Delta ]{{{\text{(NaOH}} + CaO)}}} 
    \end{array}$
  • $\begin{array}{*{20}{c}}
      {\,O\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
      {||\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
      {C{H_3} - C - O.Ag\xrightarrow[\Delta ]{{B{r_2}/CC{l_4}}}} 
    \end{array}$

Answer

Correct option: D.
$\begin{array}{*{20}{c}}
  {\,O\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
  {||\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
  {C{H_3} - C - O.Ag\xrightarrow[\Delta ]{{B{r_2}/CC{l_4}}}} 
\end{array}$
d
$\begin{array}{*{20}{c}}
  {\,\,\,O\,\,\,\,\,\,} \\ 
  {\,\,\,||\,\,\,\,\,\,} \\ 
  {C{H_3} - C - O.Ag} 
\end{array}$ ${\xrightarrow[\Delta ]{{B{r_2}/CC{l_4}}}}$ $CH_3-Br$
