Study Notes
Isomerism and Homologous Series
- The term "pentane" is misleading when referring to C5H12 molecules because there are multiple ways to arrange the atoms, implying that "pentane" is not a specific enough term.
- The general formula for any alkane is CnH2n+2, where n is the number of carbon atoms.
- For C5H12, there are multiple ways to arrange the atoms, resulting in different molecules with the same molecular formula.
Homologous Series
- A homologous series in organic chemistry is a series of compounds with the same functional group and a difference of -CH2- between successive members.
Isomerism
- Stereoisomers are non-superimposable, three-dimensional molecules with the same molecular formula and bond order.
- Isomerism refers to the existence of two or more different molecules with the same molecular formula.
- Structural isomers differ from each other in their bond order or molecular structure.
Homologous Series Characteristics
- The constant difference between successive members in a homologous series of alkanes is -CH2-.
