Is Gabriel Synthesis used to create primary Amines (pic 1), or to synthesize Amino Acids (pic 2)? I'm getting conflicting information on what Gabriel Synthesis purpose is. Or is it both and I should know only one or the other for MCAT purposes?

UWhirl claims that PCC cannot oxidize aldehydes further because it is an anhydrous oxidizing reagent that does not contain water necessary to convert aldehyde to a hydrate, an intermediate before becoming carboxylic acid. Ok, where is water in CrO3 or KMnO4 then that lets it oxidize ald to CA then?

Why is an acyl halide more reactive than an amide to a nucleophilic attack? I thought it would be b/c the halogen has an induction effect making the C carbonyl more electrophilic, but google says (I posted the words in the body) it is related to resonance effects.
