|Hydroxy||an OH group connected to a Carbon chain|
|Alkoxy||A side chain (branch) connected via an O atom to the main chain (ether)|
|amino||a NH2-group connected to the main chain.|
|nitro||a NO2-group connected to the main chain|
|ol||Just as in hydroxy: an OH-group at the main chain.
The OH-group has thus two options for nomenclature.
|al||an O atom is connected with a double bond to a primary C of the main chain|
|on||en O atom is connected with a double bond to a secondary C of the main chain|
|acid||means that a carboxylic group (COOH-) is connected to the main chain|
|(o)ate||The H of the carboxylic group was donated (and can be replaces by something else, or is negative)
Could be the rest of an acid, but also an ester
|ose||a combination of al or on with some ols|
