CHEM 2353 Fundamentals of Organic Chemistry
Organic and Biochemistry for Today (Seager & Slabaugh) www.angelo.edu/faculty/kboudreaChapter Objectives:
•Learn to recognize the aldehyde and ketone functional groups. •Learn the IUPAC system for naming aldehydes and ketones. •Learn the important physical properties of the aldehydes and ketones. •Learn the major chemical reaction of aldehydes and ketones, and learn how to predict the products of hydrogenation, oxidation, and addition of alcohol reactions. •Learn to recognize the acetal, hemiacetal, ketal, and hemiketal group, and how these are related to aldehydes and ketones.Chapter 4Aldehydes and Ketones
The Carbonyl Group
2The Carbonyl Group
• The carbonyl group (C=O) is found in aldehydes, ketones, and many other organic functional groups.
• The carbon and oxygen in the carbonyl group are sp2 -hybridized, with bond angles of 120°.•In ketones, two carbon groups are attached to the carbonyl carbon, while in aldehydesat least one hydrogen is attached to the carbon.CO

HOMethanal
(Formaldehyde)Gas at room temperature;
35-40% solution in water, called
formalin, used to preserve biological specimens, sterilize instruments, and embalm cadavers; present in wood smoke, and helps to preserve smoked meats by killing bacteria. CH 3 C CH 3 O2-Propanone
(Acetone)1 billion pounds used annually
in U.S.; good solvent for most organic compounds, and is also soluble in water; solvent for coatings such as fingernail polish and enamel paints, etc.CH 3 C HOEthanal
(Acetaldehyde)Product of oxidation of ethanol in
the liver; consuming large quantities of ethanol causes acetaldehyde to build up in bloodstream faster than it can be consumed in the liver to make other products, leading to nausea, sweating, reduced blood pressure, etc.C HOBenzaldehyde
Causes the odor of almonds
and cherries, and is also found in apricots and peaches. CH 3 C CH 2 CH 3 O2-Butanone
