The correct Answer is:
To determine which of the given compounds can give the Iodoform test, we need to analyze each compound based on its structure and the presence of specific functional groups. ### Step-by-step Solution: 1. **Identify the Compounds:** - (i) `CH₃CH₂OH` - Ethanol - (ii) `CH₃COCH₃` - Acetone - (iii) `CH₃-CH(OH)-CH₃` - 2-Propanol - (iv) `CH₃OH` - Methanol 2. **Understanding the Iodoform Test:** - The Iodoform test is used to identify the presence of methyl ketones (R-CO-CH₃) or alcohols that can be oxidized to methyl ketones. The positive result is indicated by the formation of a yellow precipitate of iodoform (CHI₃). 3. **Analyzing Each Compound:** - **Ethanol (CH₃CH₂OH)**: Ethanol has a primary alcohol structure. When oxidized, it can form acetaldehyde (which is not a methyl ketone), thus it does **not** give a positive Iodoform test. - **Acetone (CH₃COCH₃)**: Acetone is a methyl ketone. It will give a positive Iodoform test. - **2-Propanol (CH₃-CH(OH)-CH₃)**: 2-Propanol is a secondary alcohol that can be oxidized to acetone (a methyl ketone). Thus, it will also give a positive Iodoform test. - **Methanol (CH₃OH)**: Methanol is a primary alcohol and does not have the structure to form a methyl ketone upon oxidation. Therefore, it does **not** give a positive Iodoform test. 4. **Conclusion:** - The compounds that can give the Iodoform test are: - Acetone (ii) - 2-Propanol (iii) ### Final Answer: The compounds that can give the Iodoform test are (ii) Acetone and (iii) 2-Propanol.
