Ethanol, also known as ethyl alcohol, is a organic compound with the chemical formula C2H5OH. It is a volatile, flammable, colorless liquid that is commonly used as a fuel, solvent, and in alcoholic beverages.
Physical Properties: Ethanol is a volatile, flammable liquid with a boiling point of 78.37°C and a melting point of -114.1°C. It is miscible with water and has a characteristic odor.
Chemical Properties: Ethanol undergoes various chemical reactions, including combustion to produce carbon dioxide and water, oxidation to form ethanal (acetaldehyde) and then acetic acid, and esterification to form ethyl acetate.
Uses of Ethanol
Ethanol has a wide range of applications, including:
As a fuel for vehicles, either in pure form (E100) or as a blend with gasoline (E10, E85).
As a solvent for various substances, such as in the production of pharmaceuticals and perfumes.
In the manufacturing of alcoholic beverages, including beer, wine, and spirits.
When studying ethanol, it's important to focus on its chemical structure, properties, and various uses. Here are some key points to include in your study guide:
Describe the molecular structure of ethanol, highlighting the functional group and the arrangement of atoms.
Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium.
Energy
Students who demonstrate understanding can:
Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as either motions of particles or energy stored in fields.
