General Form
Naming Carboxylic Acids
Take parent name of alkane chain, drop the ‘e’, and replace it with ‘_____________’
The carboxylic acid group is _________________, so there is no need to note
the position
When numbering the carbon chain, the carbon in the carboxyl group is always
numbered ____________________
