The reagent which easily reacts with ethanol and propanol is

Options

A. Fehling solution
B. Grignard reagent
C. Schiff's reagent
D. Tollen's reagent

Answer

To determine the reagent that easily reacts with ethanol and propanol, we will analyze the options provided and their reactivity with these alcohols.

### Step 1: Identify the Structure of Ethanol and Propanol
- Ethanol (C2H5OH) has the structure: CH3-CH2-OH
- Propanol (C3H7OH) has the structure: CH3-CH2-CH2-OH

**Hint:** Remember the basic structures of the alcohols to understand their reactivity.

### Step 2: Evaluate the Given Reagents
We need to evaluate the reactivity of the following reagents with ethanol and propanol:
1. Fenton's solution
2. Grignard reagent
3. Schiff's reagent
4. Tollens' reagent

**Hint:** Consider the typical reactions that each reagent is known for.

### Step 3: Analyze Fenton's Solution
Fenton's solution is used primarily for the oxidation of organic compounds and is not known to react with alcohols like ethanol and propanol.

**Hint:** Fenton's solution is not typically used for alcohol reactions.

### Step 4: Analyze Grignard Reagent
Grignard reagents (R-MgX) are highly reactive and can react with alcohols. When Grignard reagents react with ethanol or propanol, they deprotonate the alcohol to form an alkoxide ion and an alkane.

- Reaction with Ethanol:
\[ CH3-CH2-OH + R-MgX \rightarrow R-H + CH3-CH2-O^{-}MgX^{+} \]

- Reaction with Propanol:
\[ CH3-CH2-CH2-OH + R-MgX \rightarrow R-H + CH3-CH2-CH2-O^{-}MgX^{+} \]

**Hint:** Grignard reagents are known for their reactivity with alcohols, forming alkoxides.

### Step 5: Analyze Schiff's Reagent
Schiff's reagent is used to detect aldehydes and does not react with alcohols.

**Hint:** Schiff's reagent is specific for aldehydes and does not interact with alcohols.

### Step 6: Analyze Tollens' Reagent
Tollens' reagent is also used to identify aldehydes and does not react with alcohols.

**Hint:** Like Schiff's reagent, Tollens' reagent is not reactive with alcohols.

### Conclusion
The reagent that easily reacts with both ethanol and propanol is the **Grignard reagent**.

**Final Answer:** Grignard reagent
