Action of hydrogen chloride on $\begin{array}{*{20}{c}}
  {C{H_3} - C = C{H_2}} \\ 
  |\,\,\, \\ 
  \,\,\,{C{H_3}} 
\end{array}$ and on $CH \equiv CH$ will predominantly give the compounds, respectively :-
  • A
    $\begin{array}{*{20}{c}}
      {C{H_3} - CH = C{H_2}Cl} \\ 
      {|\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
      {C{H_3}\,\,\,\,\,\,} 
    \end{array}$ and $CH_2Cl-CH_2Cl$
  • $\begin{array}{*{20}{c}}
      {C{H_3} - CCl = C{H_3}} \\ 
      {|\,\,\,\,\,\,\,} \\ 
      {C{H_3}}\,\, 
    \end{array}$ and $CH_3-CHCl_2$
  • C
    $\begin{array}{*{20}{c}}
      {C{H_3} - CH = C{H_2}Cl} \\ 
      {|\,\,\,\,\,\,\,\,\,\,\,\,} \\ 
      {C{H_3}\,\,\,\,\,\,} 
    \end{array}$ and $CH_3-CHCl_2$
  • D
    $\begin{array}{*{20}{c}}
      {C{H_3} - CH = C{H_3}} \\ 
      {|\,\,\,\,\,\,\,\,\,} \\ 
      {C{H_3}}\,\,\,\, 
    \end{array}$ and $CH_2Cl-CH_2Cl$

Answer

Correct option: B.
$\begin{array}{*{20}{c}}
  {C{H_3} - CCl = C{H_3}} \\ 
  {|\,\,\,\,\,\,\,} \\ 
  {C{H_3}}\,\, 
\end{array}$ and $CH_3-CHCl_2$
b
