Expert Answer:

Grooves method, in this method with the help of 'Lucus reagent' i.e. HCl + ZnCl2 we prepared alkyl halide from alcohol,
As we know that in alcohols to replace OH group by Cl is very difficult that's why we used ZnCl2 here, Zn has more affinity towards the oxygen hence first it form a coordinate bond with oxygen of alcohol then it becomes -O+HZnCl and it is easier for chloride ion to replace this group and form alkyl chloride.
