| Term | Definition |
|---|---|
| Nomenclature | conventions for naming compounds |
| Alkanes | simplest organic molecules with only C and H held together by single bonds |
| Str8-Chain Alkanes | have formula CnH(2n+2); are fat soluble aka nonpolar |
| Methane | CH4 |
| Ethane | CH3-CH3 |
| Propane | CH3-CH2-CH3 |
| Butane | CH3-CH2-CH2-CH3 |
| Pent- | 5 Carbons |
| Hex- | 6 Carbons |
| Hept- | 7 Carbons |
| Oct- | 8 Carbons |
| Non- | 9 Carbons |
| Dec- | 10 Carbons |
| Undec- | 11 Carbons |
| Dodec- | 12 Carbons |
| IUPAC rules | 1. identify longest back-bone 2. Number it, keeping numbers for the substituents as low as possible 3. Name substituents 4. Assign Numbers 5. Put whole name together, remembering to alphabetize substituents |
| Substituent naming | named according to appropriate prefix with ending -YL |
| When alphabetizing, these are included as part of the name | Neo-, Cyclo-, Iso- |
| Cycloalkanes | alkanes in ring form |
| Alkenes | compounds with C-C double bonds; -ene ending |
| Vinyl- | monosubstituted ethylenes |
| Allyl- | propylenes substituted at C3 position |
| Cycloalkenes | alkenes in ring form |
| Alkynes | compounds with C-C triple bonds |
| Haloalkanes | compounds with a halogen substituent |
| -OH (alcohols) | have top priority for the lowest number substituent |
| Diols | molecules with two hydroxyl groups |
| Vicinal | diols with -OH groups on adjacent carbons |
| Geminal | diols with -OH groups on same carbon |
| Ethers | have prefix alkoxy-or given common name |
| Aldehyde | terminal COH and receives number 1; -AL suffix |
| Ketone | C double bond O; -ONE suffix or -OXO prefix |
| Epoxides (ethers) | three-membered rings |
| Carboxylic Acids | ending -OIC ACID (COOH); terminal; C1 when present |
