Objectives
•
Name carboxylic acids using IUPAC nomenclature
•
Draw the structure of a carboxylic acid when given the IUPAC
name
•
Rank molecules in order of increasing boiling point based on
intermolecular forces
•
Determine the structure of carboxylic acids from various
spectral analysis techniques
•
Describe the preparation of carboxylic acids
2

aldehyde ketone carboxylic acid acid chloride amide
The Carbonyl Functional Group
•
We are going to start learning about a class of molecules that
contain the carbonyl functionality
•
There are a lot of carbonyl containing molecules

anhydride ester thioester

Synthesis of Aspirin
•
In the 1800’s common analgesics (pain killers) were salicylic
acid & sodium salicylate
•
Aspirin is not found in nature; instead, it was first synthesized in
1899 by Felix Hoffman, a German chemist at Bayer Company
