Solution

The correct options are
A $H C l + Z n C l_{2}$
C $S O C l_{2}$
D $P C l_{5}$
The reagents that can be used to prepare an alkyl halide are $H C l + Z n C l_{2}$ , $S O C l_{2}$ and $P C l_{5}$ .
$H C l + Z n C l_{2}$ is known as Lucas reagent and is used in the Groove's process for the preparation of alkyl halides from alcohols. It is also used to distinguish primary, secondary and tertiary alcohols.
$S O C l_{2}$ : Alcohols are refluxed with thionyl chloride in presence of pyridine to form thionyl chloride. The byproducts are gaseous in nature. Hence, they evaporate and leave behind only alkyl halides. This is called Darzen's method.
$P C l_{5}$ : Alcohols are converted to alkyl halides by reaction with phosphorous trichloride or phosphorous pentachloride. The reaction follows $S_{N} 2$ mechanism.
