What is denatured alcohol?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Ethanol mixed with a little methanol.
Denatured alcohol is ethanol that has been mixed with small amounts of methanol or other chemicals to make it unfit for human consumption. This process is done to avoid the taxes imposed on alcoholic beverages and to make ethanol suitable for industrial and laboratory use. Despite being chemically similar to drinking alcohol, denatured alcohol is toxic due to the additives and should never be ingested.
Other options:
-
Propanol is a different alcohol used as a solvent or disinfectant.
-
Pure Methanol is highly toxic and not denatured alcohol.
-
Pure Ethanol is consumable alcohol, not denatured.
