WebThe reaction has two uses in testing for aldehydes and ketones. First, you can just use it to test for the presence of the carbon-oxygen double bond. You only get an orange or yellow precipitate from a carbon-oxygen double bond in an aldehyde or ketone. Secondly, you can use it to help to identify the specific aldehyde or ketone. WebNational Center for Biotechnology Information WebNotes: Note that the third example is intramolecular. Mechanism: Protonation of the imine nitrogen (Step 1, arrows A and B) results in the formation of the iminium ion, which undergoes 1,2-addition by water (Step 2, arrows C and D).Transfer of a proton (Step 3, arrows E and F) followed by 1,2 elimination of ammonia (Step 4, arrows G and H) lead to … brown ceramic boy praying statue
