Learn to recognize the aldehyde and ketone functional groups. •. Learn the IUPAC system for naming Draw structural formulas for the following molecules:.
There are two systems of nomenclature of aldehydes and ketones (a) Common names Aldehydes and ketones 8 1 Nomenclature and Structure of Carbonyl Group
Aldehydes are compounds of the general formula HCHO; ketones are Both aldehydes and ketones contain the carbonyl group C O and are often referred to
Structure: While most reaction of aldehydes and ketones are at the electrophilic site there are two other reactive sites on the structure
Structure of Aldehydes and Ketones • The carbonyl carbon of an aldehyde or ketone is sp2-hybridized • The bond angle is close to 120° (trigonal planar)
Aldehydes and ketones are simple compounds which contain a Results in aldehydes or ketones depending on structure of the alkene
o In ketones the carbonyl carbon atom is connected to two other carbon atoms Structure of Aldehydes and Ketones Page 7 7 Nomenclature of Aldehydes
In addition the resonance structure on the right emphasizes that in reactions of a carbonyl group carbon acts as an electrophile and a Lewis acid The
Chapter 4 Aldehydes and Ketones Examples: Naming Aldehydes and Ketones • Draw structural formulas for the following molecules: – 3-ethyl-2-pentanone
The carbonyl group is a weak base and in acidic solution it can become protonated This makes the carbon very electrophilic (see resonance structures) and so
depending on the structure of aldehyde or ketone • Unhybridised p-orbital of carbonyl carbon form ?-bond with another half-filled p-orbital of
