MCQ
Consider the following reaction sequence

$\begin{array}{*{20}{c}}
  {\,\,C{H_3}\,\,\,\,\,\,\,\,\,\,\,} \\ 
  {|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
  {C{H_3} - C - CH = C{H_2}} \\ 
  {|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
  {\,\,C{H_3}\,\,\,\,\,\,\,\,\,\,\,} 
\end{array}\xrightarrow[{2.\,KOH - EtOH,\,heat}]{{1.\,HBr}}$

The major end product formed is :-

  • A
    $\begin{array}{*{20}{c}}
      {\,\,C{H_3}\,\,\,\,\,\,\,\,\,\,\,} \\ 
      {|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
      {C{H_3} - C - CH - C{H_3}} \\ 
      {|\,\,\,\,\,\,\,\,|\,\,\,\,\,} \\ 
      {\,\,\,\,\,\,\,C{H_3}\,\,OH\,\,\,\,\,\,\,} 
    \end{array}$
  • B
    $\begin{array}{*{20}{c}}
      {C{H_3}\,\,\,\,\,\,\,\,} \\ 
      {|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
      {C{H_3} - C - CH{{(C{H_3})}_2}} \\ 
      {|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
      {C{H_3}\,\,\,\,\,\,\,\,\,\,} 
    \end{array}$
  • C
    $\begin{array}{*{20}{c}}
      {C{H_3}\,\,\,\,\,\,\,\,} \\ 
      {|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
      {C{H_3} - C - CH = C{H_2}} \\ 
      {|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
      {C{H_3}\,\,\,\,\,\,\,\,\,\,} 
    \end{array}$
  • $\begin{array}{*{20}{c}}
      {C{H_3} - C = C - C{H_3}} \\ 
      {|\,\,\,\,\,\,\,\,\,\,|} \\ 
      {\,\,\,\,\,C{H_3}\,\,\,\,C{H_3}} 
    \end{array}$

Answer

Correct option: D.
$\begin{array}{*{20}{c}}
  {C{H_3} - C = C - C{H_3}} \\ 
  {|\,\,\,\,\,\,\,\,\,\,|} \\ 
  {\,\,\,\,\,C{H_3}\,\,\,\,C{H_3}} 
\end{array}$
