Because of its central role in organic structure and reactivity the family of carbonyl functional groups (aldehyde ketone

Nitriles have a structure similar to carbonyl ie the. C-N bond is strongly polarized and susceptible to nucleophilic attack. Nucleophiles such as Grignard.

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
