Question

Write the preparation of isopropyl chloride using the following reagents.

• A. ${PCl}_3$
• B. ${PCl}_5$
• C. ${Cl}_2$
• D. $HCl$
• E. ${SOCl}_2$

Answer 1

The correct option is A ${PCl}_3$

A) ${CH}_3-\underset{\stackrel{|}{OH}}{CH}-C{H}_3+PC{l}_3\underrightarrow{\Delta }$
$H_{3}P{O}_3+C{H}_3-\underset{\stackrel{|}{Cl}}{CH}+C{H}_3$
B) ${CH}_3-\underset{\stackrel{|}{OH}}{CH}-C{H}_3+PC{l}_5$
$\downarrow$
${CH}_3-\underset{\stackrel{|}{C{H}_3}}{CH}-Cl+POC{l}_3+HCl$
C) ${CH}_3-\underset{\stackrel{|}{OH}}{CH}-C{H}_3+Cl$
$\downarrow$
${CH}_3-\underset{\stackrel{|}{Cl}}{CH}-C{H}_3+HCl$
${\left(C{H}_3\right)}_2{-CH-OH+HCl\to CH}_3-\underset{\stackrel{|}{Cl}}{CH}-C{H}_3$ $+H_{2}O$

D) ${\left(C{H}_3\right)}_2-\underset{\stackrel{|}{OH}}{CH}\underrightarrow{SOC{l}_2}{CH}_3-\underset{\stackrel{|}{Cl}}{CH}-C{H}_3$ $+HCl$ + $S{O}_4$
