After studying this Unit, you will be
•able to
write the common  and IUPAC
names of aldehydes, ketones and
carboxylic acids;
•
write 
the 
structures 
of 
the
compounds containing functional
groups namely carbonyl and
carboxyl groups;
•
describe the important methods
of preparation and reactions of
these classes of compounds;
•
correlate physical properties and
chemical reactions of aldehydes,
ketones and carboxylic acids,
with their structures;
•
explain the mechanism of a few
selected reactions of aldehydes
and ketones;
•
understand 
various 
factors
affecting the acidity of carboxylic
acids and their reactions;
•
describe the uses of aldehydes,
ketones and carboxylic acids Objectives
Carbonyl compounds are of utmost importance to organic
chemistry They are constituents of fabrics, flavourings, plastics
and drugs 8
