12/9/2020· Reactions involving other reagents of the type Y-NH 2 Imines are sometimes difficult to isolate and purify due to their sensitivity to hydrolysis. Consequently, other reagents of the type Y–NH 2 have been studied, and found to give stable products (R 2 C=N–Y) useful in characterizing the aldehydes and ketones from which they are prepared.
6/4/2021· Aldehydes and Ketones Aldehydes and ketones have a carbonyl group (C=O) as a functional group. A ketone has two alkyl or aryl groups attached to the carbonyl carbon (RCOR’). The simplest ketone is acetone, which has two methyl groups attached to the carbonyl carbon (CH3COCH3). An aldehyde is similar to a ketone, except that instead Read more Tests for …

The Aldol reaction involves the dimerization of an aldehyde or a ketone. In the presence of sodium hydroxide, aldehyde or ketone is converted to an enolate ion, but not all the carbonyl molecules are converted and so the enolate ion can undergo a nucleophilic addition on ‘free’ aldehyde or ketone. The product is a β-hydroxyaldehyde or β
