Acetone is a colorless, volatile, and flammable liquid with the chemical formula (CH3)2CO. It is the simplest and smallest ketone, which is a type of organic compound that contains a carbonyl group (C=O) bonded to two carbon atoms.
In this article, we will study in detail about acetone and structural formula of acetone.
1. Acetone- Definition
Acetone is a colorless, volatile, and flammable liquid with the chemical formula (CH3)2CO. It is the simplest and smallest ketone, which is a type of organic compound that contains a carbonyl group (C=O) bonded to two carbon atoms.
Acetone is a common solvent that is used in many industries, including pharmaceuticals, cosmetics, and plastics. It is also used as a cleaning agent and as a fuel additive. In the body, acetone is produced as a byproduct of the breakdown of fats.
Acetone has a distinctive sweet odor and is highly flammable. It should be handled with care and stored in a cool, dry place away from sources of heat and flame.
2. Properties of Acetone
Acetone is a useful and versatile solvent but should be handled with care due to its flammability and potential health hazards.
Here are some of the properties of acetone:
- Physical state: Acetone is a colorless liquid that is highly volatile, meaning it evaporates quickly at room temperature.
- Odor: Acetone has a sweet, pungent odor that can be detected at low concentrations.
- Solubility: Acetone is highly soluble in water and many organic solvents.
- Flammability: Acetone is highly flammable and can ignite at low temperatures. It has a flash point of -20°C.
- Density: The density of acetone is 0.789 g/cm³ at 20°C.
- Boiling point: The boiling point of acetone is 56.1°C, which is relatively low.
- Chemical reactivity: Acetone is a relatively stable compound, but it can react with strong oxidizing agents and acids.
- Health effects: Acetone can be harmful if it is ingested, inhaled, or comes into contact with the skin or eyes. It can cause irritation, headaches, dizziness, and other health problems. Acetone is also a central nervous system depressant and can cause drowsiness or unconsciousness in high concentrations.
