Organic Acids
-
Carboxylic acids contain the carboxylic acid group.
-
Their names end with –oic acid.
-
The functional group on the carboxylic acids can be summarised as -COOH. However the two oxygens aren’t actually joint together:
-
The simplest carboxylic acid groups contain an alkyl group attached to a carboxylic acid group- RCOOH.
-
Two carboxylic acid groups can also be present. The suffix “dioic acid” is then used:
-
A carboxylic acid group can also be attached to a benzene ring:
-
The –OH group on the carboxylic acid group can be replaced to form a wide range of acid derivatives:
