carbonyl compounds, represented by the general structure C=O are conveniently classified on the basis of the type of groups(i.e.,G and G') that are attached to the carbonyl function. The attached groups are classified as follows:
1.Type A groups: Hydrogen or organic frameworks in which the carbon attached to the C=O is sp3-hybridized. This includes H-and alkyl groups, such as CH3-, and substituted alkyl groups, such as C6H5CH2-, etc.
2.Type B and B' groups: Organic frameworks to which the carbon attached to the C=O is sp2- or sp- hybridized. If the attached groups is C=C- or C=C-, it is designated as a type B groups; if it is an aryl ring it is classed as a type B' groups.
3.Type C groups: Groups other than carbon or hydrogen. This includes halogen, -OH, -NH2, etc.
