| Question | Answer |
| General Formula | Simplest algebraic formula of a member of a homologous series (ie) CnH2n+2 for Alkanes (non-cyclic) |
| Empirical Formula | Simplest whole number ratio of atoms present in a compound. |
| Molecular Formula | Actual whole number ratio of atoms present in a compound. |
| Structural Formula | The minimal detail that shows the arrangement of atoms in a molecule (ie) CH3CH2CH2CH3 for butane |
| Displayed Formula | A formula that shows the relative positioning of ALL atoms and bonds within a structure |
| Skeletal Formula | A simplified organic formula, shown by removing hydrogen atoms from carbon chains, leaving just a carbon skeleton and associated functional groups. |
| Hydrocarbon | A compound that contains only Carbon and Hydrogen atoms |
| Functional Group | Group of atoms in a molecule responsible for the characteristic reactions of a compound |
| Homologous Series | A series of compounds having the same functional group & general formula but with each successive member differing by CH2 |
| Structural Isomer | Molecules with the same molecular formula but with different structural formula |
| Stereoisomer | Compounds with the same structural formula but with a different arrangement of atoms in space. |
| E/Z isomer | An example of stereoisomerism, in terms of restricted rotation about a C=C and the requirement for two different groups to be attached to each carbon atom of the C=C bond |
| Cis / trans isomer | A special case of E/Z isomerism in which two of the substituent groups are the same |
| Bond Fission | The breaking of a covalent |
| Homolytic fission | The breaking of a covalent bond, with one of the shared pair of electrons going to each atom, forming two radicals. |
| Heterolytic Fission | The breaking of a covalent bond with both of the shared pair of electrons going to one of the atoms forming ions |
| Electrophile | An electron pair acceptor |
| Nucleophile | An electron pair doner |
