Study Notes
Organic Chemistry
- Branch of chemistry that deals with the study of carbon-containing compounds and their properties, reactions, and synthesis.
- Organic compounds can be found in all living things and are the basis of all life.
- Characteristics of organic compounds:
- Contain carbon and hydrogen atoms
- May contain other elements such as oxygen, nitrogen, sulfur, and phosphorus
- Typically have a complex molecular structure
- Can be found in nature or synthesized in a laboratory
- Subfields of organic chemistry:
- Bioorganic chemistry: study of the chemical processes in living organisms
- Organometallic chemistry: study of compounds containing carbon-metal bonds
- Physical organic chemistry: study of the physical properties and reactions of organic compounds
Etard Reaction
- A type of organic reaction used to prepare aldehydes from methyl ketones.
- Reaction mechanism:
- The methyl ketone is treated with a mixture of chromic acid and sulfuric acid.
- The chromic acid oxidizes the methyl group to form an aldehyde.
- The resulting aldehyde is then separated from the reaction mixture.
- Important aspects of the Etard reaction:
- The reaction is highly specific and only oxidizes the methyl group.
- The reaction conditions are critical, and the temperature and acid concentration must be carefully controlled.
- The Etard reaction is often used in the synthesis of complex organic molecules, such as fragrances and pharmaceuticals.
