Which of the following does not produce salt with hydrochloric acid ?

Options

A. Ethylamine
B. aniline
C. Acetamide
D. phenol

Answer

To determine which of the given compounds does not produce a salt when reacted with hydrochloric acid (HCl), we will analyze each compound one by one.

### Step 1: Analyze Ethyl Amine
- **Compound**: Ethyl Amine (CH3CH2NH2)
- **Reaction with HCl**: Ethyl amine reacts with HCl to form ethyl ammonium chloride.
- Reaction:
\[ \text{CH}_3\text{CH}_2\text{NH}_2 + \text{HCl} \rightarrow \text{CH}_3\text{CH}_2\text{NH}_3^+\text{Cl}^- \]
- **Conclusion**: Ethyl amine produces a salt.

### Step 2: Analyze Aniline
- **Compound**: Aniline (C6H5NH2)
- **Reaction with HCl**: Aniline reacts with HCl to form phenyl ammonium chloride.
- Reaction:
\[ \text{C}_6\text{H}_5\text{NH}_2 + \text{HCl} \rightarrow \text{C}_6\text{H}_5\text{NH}_3^+\text{Cl}^- \]
- **Conclusion**: Aniline produces a salt.

### Step 3: Analyze Acetamide
- **Compound**: Acetamide (CH3CONH2)
- **Reaction with HCl**: Acetamide reacts with HCl to form acetamide hydrochloride.
- Reaction:
\[ \text{CH}_3\text{CONH}_2 + \text{HCl} \rightarrow \text{CH}_3\text{C(O)NH}_3^+\text{Cl}^- \]
- **Conclusion**: Acetamide produces a salt.

### Step 4: Analyze Phenol
- **Compound**: Phenol (C6H5OH)
- **Reaction with HCl**: Phenol does not react with HCl to form a salt. Instead, it remains as phenol and does not produce any ionic species.
- Reaction:
\[ \text{C}_6\text{H}_5\text{OH} + \text{HCl} \rightarrow \text{No reaction} \]
- **Conclusion**: Phenol does not produce a salt.

### Final Answer
The compound that does not produce a salt with hydrochloric acid is **Phenol (C6H5OH)**.
