What is C2H5OH? Important knowledge about C2H5OH.

1. Definition of C₂H₅OH:

C₂H₅OH is the chemical formula of ethyl alcohol, an organic compound in the family of alcohols. Ethyl alcohol is also known by other names such as ethanol, ethylic alcohol, or simply alcohol. Its English name is ethanol or ethyl alcohol.

The structure of the C₂H₅OH molecule includes 2 carbon atoms (C), 6 hydrogen atoms (H), and one oxygen atom (O). The molecular weight is 46.07 g/mol. Ethyl alcohol does not form ions in solution.

2. Properties of C₂H₅OH

2.1 Physical properties of ethyl alcohol: It is a transparent, colorless liquid with a characteristic smell. Its pH is around 7, which is neutral.

2.2 Chemical properties of ethyl alcohol: It is easily oxidized, can react with acids and salts to form other compounds.

3. Common chemical equations of C₂H₅OH:

Ethyl alcohol can react with metals, acids, non-metals, and salts. For example:

• Reaction with acid, for example: C₂H₅OH + HCl -> C₂H₅Cl + H₂O
• Reaction with salt, for example: C₂H₅OH + Na -> C₂H₅ONa + H₂
• Reaction with non-metals, for example: C₂H₅OH + O₂ -> CO₂ + H₂O

4. Synthesis of C₂H₅OH

4.1 There are many methods to synthesize ethyl alcohol in the laboratory, such as the reaction between ethylene and water in an acid environment or from the fermentation of sugar.

4.2 On an industrial scale, ethyl alcohol is typically produced from the fermentation of sugar by saccharomyces cerevisiae yeast or from the hydration of ethylene.
