General Aim
Learning Objectives (ILOs)
Method
Identi?cation and Di?erentiation between Aldehydes and Ketones through the chemical detection of aldehyde and ketone carbonyl groups, respectively. Detection of the presence of aldehydes and ketones using special and speci?c reagents.Theoretical Background/Context
De?ne and di?erentiate between carbonyl groups of aldehydes and ketones theoretically through their chemical structure.
Classify organic compounds containing carbonyl groups into aldehydes and ketones. Compare between aldehydes and ketones in terms of chemical structures, properties and reactions. Select the appropriate reagents to di?erentiate between aldehydes and ketones.Identify aldehydic and ketonic functional groups in organic compounds by performing 2,4-dinitrophenylhydrazine test.
Di?erentiating between aldehydes and ketones by Tollen"s, Schi?"s Test and Fehling"s Tests.Aldehydes and ketones are two classes of organic compounds that possess at least one carbonyl group (C=O). Aldehydes
(R - CHO) are characterized by having a terminal CHO in their structure, while ketones (R quotesdbs_dbs10.pdfusesText_16
