Study Notes
Organic Chemistry
- Molecules containing carbon are classified as organic compounds.
- Carbon dioxide and molecules without carbon are classified as inorganic compounds.
Hydrocarbons
- A hydrocarbon is an organic compound composed of only hydrogen and carbon atoms.
- Hydrocarbons follow Huckel's Rule, which states that the number of π electrons (π e-) is equal to 4n + 2.
Aromatic Compounds
- If an organic compound does not follow the four general factors of an aromatic compound, it is classified as aliphatic.
- The four general factors of an aromatic compound are:
- Cyclic (closed structure with no terminal unsaturated point)
- Contain pi bonds
- Follow Huckel's Rule (π e- = 4n + 2)
- Other factors (not specified)
Hydrocarbon Derivatives
- Hydrocarbon derivatives are formed when a functional group is substituted at one or more positions in a hydrocarbon.
Tetravalent Carbon Atom
- The tetravalent carbon atom is the building block of structural organic chemistry.
- Carbon compounds can be formulated with four covalent bonds to each carbon, regardless of whether the combination is with carbon or another element.
Lewis Structure
- A Lewis structure is a representation of bonded electron pairs in covalent bonds as lines.
Importance of Carbon
- Carbon is important because it can form up to four bonds (single, double, or triple) in rings or in chains.
- Carbon is versatile and can form a wide variety of compounds.
Study of Organic Chemistry
- Organic chemistry involves the study of carbon and its compounds.
- Organic chemistry also involves the study of hydrocarbon compounds and their derivatives.
Learn about Huckel's Rule which states that if the number of pi electrons in a cyclic compound follows the formula 4n + 2, then it is aromatic. If the compound does not meet the criteria for an aromatic compound, then it is classified as aliphatic.
