Which of the following compound will not give positive test with `NaHCO_(3)`.?
`{:("Phenol"",",CH_(3)COOH",",CH_(3)CH_(2)SO_(3)H",",CH_(3)C-=CH",",CH_(3)CH_(2)OH","),("Phthalic acid" ,"Salicylic acid" ",","Cinammic acid","Lactice acid",P-"Cresol"):}`

Explanation

To determine which of the given compounds will not give a positive test with sodium bicarbonate (NaHCO₃), we need to understand the nature of the compounds listed and their reactivity with NaHCO₃. Sodium bicarbonate reacts with acids to produce carbon dioxide (CO₂) gas, which is the basis for the positive test.

### Step-by-Step Solution:

1. **Understanding NaHCO₃ Reaction**:
- Sodium bicarbonate reacts with acids to produce CO₂ gas. Therefore, compounds that are acidic will give a positive test, while neutral or basic compounds will not.

2. **Analyzing Each Compound**:
- **Phenol (C₆H₅OH)**:
- Phenol is a weak acid but primarily behaves as a weak base. It does not produce CO₂ with NaHCO₃.
- **Conclusion**: Will not give a positive test.

- **Acetic Acid (CH₃COOH)**:
- Acetic acid is a carboxylic acid and will react with NaHCO₃ to produce CO₂.
- **Conclusion**: Will give a positive test.

- **Ethane Sulfonic Acid (CH₃CH₂SO₃H)**:
- This is a sulfonic acid, which is a strong acid. It will react with NaHCO₃ to produce CO₂.
- **Conclusion**: Will give a positive test.

- **Propyne (CH₃C≡CH)**:
- Propyne is an alkyne and is not acidic. It will not react with NaHCO₃.
- **Conclusion**: Will not give a positive test.

- **Ethanol (CH₃CH₂OH)**:
- Ethanol is an alcohol and is neutral in nature. It will not react with NaHCO₃.
- **Conclusion**: Will not give a positive test.

- **Phthalic Acid**:
- Phthalic acid is a dicarboxylic acid and will react with NaHCO₃ to produce CO₂.
- **Conclusion**: Will give a positive test.

- **Salicylic Acid**:
- Salicylic acid is also a carboxylic acid and will react with NaHCO₃ to produce CO₂.
- **Conclusion**: Will give a positive test.

- **Cinnamic Acid**:
- Cinnamic acid is a carboxylic acid and will react with NaHCO₃ to produce CO₂.
- **Conclusion**: Will give a positive test.

- **Lactic Acid**:
- Lactic acid is a carboxylic acid and will react with NaHCO₃ to produce CO₂.
- **Conclusion**: Will give a positive test.

- **p-Cresol**:
- p-Cresol is similar to phenol and behaves as a weak base. It will not react with NaHCO₃.
- **Conclusion**: Will not give a positive test.

3. **Final List of Compounds Not Giving Positive Test**:
- The compounds that will not give a positive test with NaHCO₃ are:
- Phenol
- Propyne
- Ethanol
- p-Cresol

### Answer:
The compounds that will not give a positive test with NaHCO₃ are **Phenol, Propyne, Ethanol, and p-Cresol**.
