Substituent
suffix = -oic acid e.g.
ethanoic acid
Substituent prefix = carboxy

|
- The root name is based
on the longest chain including the carboxylic acid group.
- Since the carboxylic
acid group is at the end of the chain, it must be C1.
- The carboxylic acid suffix
is appended after the hydrocarbon suffix minus the "e" : e.g.
-ane + -oic acid = -anoic acid etc.
- Functional group is a carboxylic acid, therefore suffix = -oic acid
- Hydrocarbon structure is an alkane therefore -ane
- The longest continuous chain is C4 therefore root = but
butanoic acid
