Select the appropriate reagents to di erentiate between aldehydes and ketones. Identify aldehydic and ketonic functional groups in organic compounds by
numbering starts from the end with the aldehyde. - methyl group is therefore on 4th carbon. 4-methylpentanal. The simplest aromatic aldehyde and ketone are:.
Qualitative tests for Ketones and Aldehydes. - Aldehydes and ketones share the carbonyl functional group which features carbon doubly bonded to oxygen.
