- HydrocarbonsA hydrocarbon is a compound that contains hydrogen and carbon atoms only.
- Saturated and Unsaturated HydrocarbonsA saturated hydrocarbon contains only single bonds between its carbon atoms.
- Cyclic CompoundsIn many organic compounds the carbon atoms form open chains, which may be straight or branched.
- Types of FormulaeOrganic molecules can be shown with several types of formula.
- Functional GroupsA functional group is an atom or group of atoms in a molecule that is responsible for the characteristic chemical reactions of that molecule.
- Homologous SeriesA homologous series is a family of organic compounds that: 1. have the same functional group; 2. have the same general formula; 3. differ from the…
- Naming Organic CompoundsOrganic compounds are named using the IUPAC system, so each name describes exactly one structure.
- Practice Question - 1Question Compound A has the structural formula CH3CH2CH(CH3)CH2OH.
- Practice Question - 2Question An alkane X has a relative molecular mass of 86.0.
- Practice Question - 3Question A hydrocarbon Y contains 85.7% carbon by mass.
- Structural IsomerismStructural isomers are compounds with the same molecular formula but a different structural formula.
- StereoisomerismStereoisomers have the same structural formula (the atoms are bonded in the same order) but a different arrangement of the atoms in space.
- Geometric Isomers E-Z NotationThe cis-trans names only work when the same group is on both carbons of the C=C.
