Solution

The correct option is C 3
c)
$C H_{3} - C H_{2} - C H_{2} - C \equiv C H N a N H_{2} - ---- \to$

$C H_{3} - C H_{2} - C H_{2} - C \equiv C - N a C H_{3} C H_{2} C H_{2} B r - --------- \to$

$C H_{3} - C H_{2} - C H_{2} \equiv C - C H_{2} - C H_{2} - C H_{3} 4 - O c t y n e H_{2} - \to P d$
