Name one reagent which is used for the distinction of primary, secondary and tertiary alcohols.

Explanation

To distinguish between primary, secondary, and tertiary alcohols, we can use Lucas reagent, which is a mixture of concentrated hydrochloric acid (HCl) and anhydrous zinc chloride (ZnCl2). Here’s a step-by-step explanation of how this reagent works:

### Step-by-Step Solution:

1. **Identify the Reagent**: The reagent used for distinguishing between primary, secondary, and tertiary alcohols is Lucas reagent, which consists of concentrated hydrochloric acid (HCl) and anhydrous zinc chloride (ZnCl2).

2. **Reactions with Tertiary Alcohols**:
- When a tertiary alcohol (e.g., isobutyl alcohol) is treated with Lucas reagent, it reacts immediately to form a chloroalkane (e.g., 2-chloro-2-methylpropane) and water.
