Understanding Methanol and Ethanol – Key Differences
Methanol and ethanol are both types of alcohol, but they have different chemical structures, uses, and effects on humans. Both are organic compounds containing a hydroxyl (-OH) group, but their properties and applications vary significantly.
Understanding the difference between methanol and ethanol is crucial, as one is safe for consumption while the other is highly toxic. Let’s explore these two alcohols in detail.
Methanol
Methanol, also known as wood alcohol, is the simplest type of alcohol with the chemical formula CH₃OH. It is highly toxic and can cause severe poisoning if ingested.
Ethanol
Ethanol, also known as ethyl alcohol, is a safe, consumable alcohol commonly found in alcoholic beverages, hand sanitisers, and fuel. It is produced by the fermentation of sugars in plants.

FAQs on Difference Between Methanol and Ethanol
1. What is the major difference between methanol and ethanol?
Methanol is highly toxic and used in industrial applications, while ethanol is safe for human consumption in alcoholic beverages.
2. Can methanol be consumed?
No, methanol is highly poisonous and can cause blindness, organ failure, or death if ingested.
3. How can methanol poisoning be treated?
Methanol poisoning is treated using ethanol or fomepizole, which prevents the toxic breakdown of methanol in the body.
4. Why is ethanol used in alcoholic beverages?
Ethanol is fermented from sugars and is safe to drink in controlled amounts, unlike methanol, which is toxic.
5. How can you distinguish between methanol and ethanol?
Methanol burns with a light blue flame and has a mild smell.
Ethanol burns with a yellow flame and has a stronger alcoholic odor.
Methanol reacts with water to absorb moisture, while ethanol does not absorb water as much.
6. Is ethanol used as a fuel?
Yes, ethanol is used in biofuels and fuel additives to reduce carbon emissions in vehicles.
7. What happens if ethanol is consumed in excess?
Excess ethanol consumption leads to alcohol poisoning, liver damage, addiction, and long-term health problems.
8. Can methanol be found in home products?
Yes, methanol is present in antifreeze, windshield washer fluids, industrial solvents, and fuel additives.
9. Why is ethanol used in sanitizers?
Ethanol is an effective disinfectant that kills bacteria and viruses, making it ideal for use in hand sanitizers.
10. Can methanol be converted into ethanol?
No, methanol and ethanol have different chemical structures and properties, and methanol cannot be safely converted into ethanol.
