Which of the following reaction(s) can be used for the preparation of alkyl halides?

I. CH3CH2OH+HCl→Anhyd.ZnCl2C{H}_{3}C{H}_{2}OH+HCl\overset{Anhyd. ZnC{l}_{2}}{\rightarrow }CH3​CH2​OH+HCl→Anhyd.ZnCl2​

II. CH3CH2OH+HCl⟶C{H}_{3}C{H}_{2}OH+HCl\longrightarrowCH3​CH2​OH+HCl⟶

III. (CH3)3COH+HCl⟶{(C{H}_{3})}_{3}COH+HCl\longrightarrow(CH3​)3​COH+HCl⟶

IV. (CH3)2CHOH+HCl→Anhyd.ZnCl2{(C{H}_{3})}_{2}CHOH+HCl\overset{Anhyd. ZnC{l}_{2}}{\rightarrow }(CH3​)2​CHOH+HCl→Anhyd.ZnCl2​
