In the preparation of ethyl chloride by the reaction the major reason for using anhydrous ZnCl₂ as a catalyst is that -

Answer: It coordinates with oxygen of ethyl alcohol and increases the leaving group ability of the –OH group — ZnCl₂ (Lucas reagent component) coordinates with the alcohol oxygen, making –OH a better leaving group.
