1 - butanol

1-chlorobutane

but-1-ene

Open in App

Solution

1). By using the catalyst $r e d p h o s p h o r o u s / I_{2}$

$C H_{3} C H_{2} C H_{2} C H_{2} 1 - b u t a n o l O H r e d p h o s p o r o u s / I_{2} - ------------- \to C H_{3} C H_{2} C H_{2} C H_{2} I 1 - i o d o b u t a n e + H_{2} O$

2). In presence of dry Acetone [ Finkelstein reaction]

$C H_{3} C H_{2} C H_{2} C H_{2} C l + N a I C H_{3} O H - ---- \to A c e t o n e C H_{3} C H_{2} C H_{2} C H_{2} I + N a C l$

3). By using Peroxide [ Anti-Markovnikov's Addition]
$C H_{3} C H_{2} C H = C H_{2} + H B r p e r o x i d e - ----- \to C H_{3} C H_{2} C H_{2} C H_{2} B r N a I, d r y a c e t o n e - ------------ \to C H_{3} C H_{2} C H_{2} C H_{2} I$
