Select the correct match of the alcohol with the Lucas reagent.

Options

A. Primary alcohol` rarr `produces turbidity immediately
B. Secondary alcohol` rarr` produces turbidity immediately
C. Tertiary alcohol `rarr` produces turbidity immediately
D. All of the above

Answer

To solve the question of selecting the correct match of alcohol with the Lucas reagent, we need to understand how different types of alcohols react with the Lucas reagent.

### Step-by-Step Solution:

1. **Understand the Lucas Reagent**:
- The Lucas reagent is a mixture of concentrated hydrochloric acid (HCl) and zinc chloride (ZnCl2). It is used to differentiate between primary, secondary, and tertiary alcohols based on their reactivity.

**Hint**: Remember that the Lucas reagent is used to test the reactivity of alcohols, particularly in distinguishing between primary, secondary, and tertiary alcohols.

2. **Reactivity of Alcohols with Lucas Reagent**:
- **Primary Alcohols**: When a primary alcohol is added to the Lucas reagent, there is no immediate reaction. Turbidity (cloudiness) is only observed upon heating, indicating a slow reaction.
- **Secondary Alcohols**: Secondary alcohols react with the Lucas reagent but show turbidity after a few minutes (around 5-6 minutes).
- **Tertiary Alcohols**: Tertiary alcohols react immediately with the Lucas reagent, producing turbidity right away.

**Hint**: Focus on the time taken for turbidity to appear when alcohols are mixed with the Lucas reagent. This will help you identify the type of alcohol.

3. **Identify the Correct Match**:
- Based on the above information:
- If the alcohol is primary, there will be no immediate turbidity.
- If the alcohol is secondary, turbidity will appear after a few minutes.
- If the alcohol is tertiary, turbidity will appear immediately.

**Hint**: Look for the option that describes the immediate turbidity for tertiary alcohols, delayed turbidity for secondary alcohols, and no turbidity for primary alcohols.

4. **Select the Correct Option**:
- Given the descriptions of how each type of alcohol reacts with the Lucas reagent, the correct match is the one that corresponds to tertiary alcohol showing immediate turbidity.

**Hint**: Verify each option against the reactivity patterns discussed to ensure you select the correct match.

### Final Answer:
The correct match of the alcohol with the Lucas reagent is **Option number 3**, which corresponds to the tertiary alcohol showing immediate turbidity.
