1) My book says that we can distinguish between 2 hydroxy butanoic acid (A) and 3 hydroxy butanoic acid (B) by haloform tests. It says that B gives positive haloform test. I am fine with it.
I don't get why A doesnot give positive test as it is also a sec. alcohol .
2)In the base-catalysed hydrolysis of amides, they undergo nucleophilic addition of OH- and finally form acetate.
In hoffmann degradation, we use OH- (of an alkali) where it extracts a proton from the -NH2 group and does not add to the amide.
Why is the action of same OH- different in two cases?
Any help appreciated.
