  • $CH_3 -CH = CH -C  \equiv  CH \to Pent -2-en-4-yne$
  • D
    $\begin{array}{*{20}{c}}
      {C{H_3}\,\,\,\,\,\,\,\,} \\ 
      {|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\

      {C{H_3}\,\,\,\,\,\,\,\,\,} 
    \end{array}$ $\to $ $2, 2-$ Dimethyl propanamine

Answer

Correct option: C.
$CH_3 -CH = CH -C  \equiv  CH \to Pent -2-en-4-yne$
c
$CH_3 -CH = CH -C  \equiv  CH \to Pent - 2- en - 4 - yne$

$Pent -3- enyne$ or $pent-3-en-1-yne$
