Denatured alcohol with colour and foul smell is made now a days by mixing ethanol with
Show Hint
Methanol was traditionally used but is highly toxic.
Updated On: Apr 28, 2026
- Methanol
- $ZnSO_{4}$ and thiophene
- $CuSO_{4}$ and pyridine
- $FeSO_{4}$ and furan
- $Fe_{2}(SO_{4})_{3}$ and hexane
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Denaturation makes alcohol unfit for drinking by adding toxic/unpleasant substances.
Step 2: Meaning
Coloring and odorizing agents are used for easy identification.
Step 3: Analysis
$CuSO_4$ (Copper sulphate) gives a blue color, and pyridine gives a foul, nauseating smell.
Step 4: Conclusion
The additives are $CuSO_4$ and pyridine. Final Answer: (C)
