Naming Alkanols (Alcohols) |
Key Concepts
- functional group -OH
- number longest carbon chain that includes OH group and gives the lowest combination of numbers
| 1 OH group = alkanol |
| 2 OH group = alkanediol |
| 3 OH group = alkanetriol |
- name branches as for branched chain alkanes
- Isomers of alkanols are classified depending on the location of the -OH functional group
| Classification |
