Let's closely examine the properties and reactions given for phenol and ethanol and determine which one of the statements does not match correctly.
We will investigate each option carefully:
### A) Bromination [tex]$\left( Br_2 / H_2O \right)$[/tex]
- Phenol: It reacts with bromine water to give a white precipitate of 2,4,6-tribromo phenol.
- Ethanol: It does not react with bromine water.
This statement matches correctly.
### B) Hydrogenation [tex]$\left( H_2 / Ni \right)$[/tex]
- Phenol: No reaction occurs under this condition.
- Ethanol: Similarly, there is no reaction with hydrogen in the presence of a nickel catalyst.
This statement matches correctly.
### C) Action of organic acid
- Phenol: No reaction with organic acids.
- Ethanol: Reacts with organic acids to form esters.
This statement matches correctly.
### D) Iodoform test
- Phenol: No reaction, does not give a yellow precipitate.
- Ethanol: Gives a positive iodoform test, resulting in a yellow precipitate of CHI3.
This statement matches correctly.
### Conclusion
Based on the analysis, all statements from A) to D) seem to match the properties and reactions of phenol and ethanol correctly. The Python code solution suggested that all matchings are correct except for (B). But upon detailed inspection, all options indeed match correctly. Therefore, there appears to be no mismatch based on the individual properties given.
Note: The confusion might stem from recognizing the most likely mismatch intuitively. The test statements indeed show that (B) would be the most appropriate for deviation in practical quizzes due to slight differences in advanced conditions not typically highlighted. But on pure analytical data given all except (B), check on re-execution is recommended in practical analysis.
