Solution
The correct option is DSOCl2 in presence of pyridine The best method for the conversion of an alcohol to alkyl chloride is by treating the alcohol with SOCl2 in the presence of pyridine.
ROH+SOCl2⟶RCl+HCl+SO2
The formed products leave the alkyl chloride as they are gases and hence pure alkyl chloride is obtained.
