What is the Difference Between Acetone and Ethanol?

🆚 Go to Comparative Table 🆚

Acetone and ethanol are both organic compounds, but they have distinct chemical and physical properties. The key difference between acetone and ethanol lies in their chemical structure:

  • Acetone is a ketone with the chemical formula (CH3)2CO, containing a carbon atom with a double bond with an oxygen atom and two single bonds with hydrogen atoms.
  • Ethanol is an alcohol with the chemical formula C2H6O, containing a carbon atom with a hydroxyl group (C-OH).

Here are some notable differences between acetone and ethanol:

  1. Organic Compound Type: Acetone is a ketone, while ethanol is an alcohol.
  2. Chemical Structure: Acetone has a C=O bond in its chemical structure, whereas ethanol has a C-OH bond.
  3. Odor: Acetone has a distinct, mild scent, while ethanol has a pleasant, sweet scent.
  4. Toxicity: Acetone is non-toxic, while ethanol can be toxic in certain forms, such as denatured alcohol.

Both acetone and ethanol are versatile chemical compounds used in various industries, including automotive, plastics, and cleaning. However, the choice between them depends on their specific properties and the intended application.

Comparative Table: Acetone vs Ethanol

Here is a table comparing the differences between acetone and ethanol:

Property Acetone Ethanol
Chemical Formula (CH3)2CO C2H6O
Classification Ketone Alcohol
Solubility in Water Miscible Soluble
Boiling Point 101°C (213°F) 78.5°C (173°F)
Melting Point -95°C (-139°F) -114°C (-175°F)
Flammability Highly flammable Flammable
Uses Industrial and household cleaning, solvent in pharmaceuticals, cosmetics, and fuel production Production of alcoholic beverages, fuel source, and various industrial applications

Acetone is a ketone with the chemical formula (CH3)2CO, while ethanol is an alcohol with the chemical formula C2H6O. Acetone is a colorless, volatile, flammable liquid with a pungent, irritating odor. Ethanol, on the other hand, is commonly found in alcoholic beverages and is used as a fuel source in many countries.
