Solution

The correct option is C c) SOCl2/ Pyridine
Answer: c
Explanation: The best method of preparation of alkyl halides is a reaction of an alcohol with $S O C l_{2}$ / Pyridine because by-products formed in the reaction are SO2 and HCl which are in gaseous form and escape into the atmosphere leaving behind pure alkyl chlorides.
$C H_{3}$ $C H_{2} - O H$ + $S O C l_{2}$ → $C H_{3} C H_{2} - C l$ + $S O_{2} ↑$ + $H C l ↑$
