Study Notes
- Organic chemistry originated from alchemy and the search for the philosopher's stone and the elixir of life.
- Lavoisier distinguished organic compounds from inorganic ones by identifying the presence of organogenic elements (C, N, O, H) in living organisms.
- Wöhler's synthesis of oxalic acid from inorganic materials disproved the theory of vitalism.
- There are approximately 4 million known organic compounds, mostly composed of organogenic elements.
- Carbon atoms can form up to four strong covalent bonds and can bond with each other to create chains and rings.
- Different bonding arrangements of carbon atoms can result in isomers, which have the same molecular formula but different structures.
- Heteroatoms (O, N, P, S, halogens) can also participate in molecular formation with carbon and hydrogen in organic compounds.
- Many drugs and dyes are synthesized from natural compounds.
- Organic compounds are more susceptible to decomposition during experiments than inorganic ones.
- Organic chemistry has practical applications in various fields, including medicine and materials science.
