Answer:
When primary alcohol or secondary alcohol is combined with HCl gas in the presence of Lewis acid (anhydrous ZnCl2), primary and secondary alkyl chloride or chloro-alkane is generated respectively, then this method is named as Grove’s process. The reaction continues via the SN2 mechanism. Below is an instance of Grove’s process.
CH3CH2OH + HCl → CH3CH2Cl + H2O
Ethanol reacts with hydrochloric acid through SN2 mechanism to produce chloroethane and water.
