Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Understanding Lucas Test**: The Lucas test is a qualitative test used to differentiate between primary, secondary, and tertiary alcohols based on their reactivity with Lucas reagent, which is a mixture of hydrochloric acid (HCl) and anhydrous zinc chloride (ZnCl2). 2. **Role of Anhydrous ZnCl2**: Anhydrous ZnCl2 acts as a catalyst in the Lucas test. It helps in the formation of the reactive species that can react with alcohols. 3. **Reaction Mechanism**: - When alcohol is treated with HCl in the presence of ZnCl2, the ZnCl2 reacts with HCl to form a complex, which is ZnCl4^2-. ...
