MCAT Organic Chemistry > Acid Derivatives
Acid derivatives are very important molecules for biological processes, particularly phosphate esters, which can be found in membranes, nucleic acids and metabolic reactions.
Acid derivatives refer to compounds with a carboxyl group and are one of the most widely found functional groups in chemistry and biochemistry. These compounds can be formed by adding RCOOH + SOCL2, PCL3, or PBr3. Examples of these include...
They can undergo many different nucleophillic substitutions
H2O yields carboxylic acid
ROH yields an ester
NH3 yields an amide
- Acid Chlorides
The suffix used in IUPAC naming of acid chlorides is “-oyl chloride”.
For anhydrides, it is “-oic anhydride”
For amides it is “-amide”
For esters, it is “-oate”.
The chart below demonstrates examples of IUPAC naming schemes for these classes of compounds:
