describe the preperation of CA from amide in basic conditions.
The base (in H2O) backside attacks the carbonyl group(addition) forcing a pi bond to break adding a lone pair on the oxygen. Next, (elimination) the double bond re-establishes and NH2- leaves. The base steals a proton from the OH group on the carbonyl (deprotonation). A proton is regained from H20 to restore then carboxylic acid.
