    In case of base catalysed rexn... hydroxide ion is better leaving group than amide ion so shouldn't hydroxide ion leave?

    If the NH2 is protonated first like it mentions in the annotation at 8:13 then at what following step would you have an irreversible reaction? Because then you end up with NH3 instead of NH2 floating around to deprotonate the remaining OH group

    When do we specifically need to do acidic hydrolysis or how can we distinguish that either we should opt acidic hydrolysis or basic hydrolysis

    Can you use water as the base to take the proton in the acid hydrolysis?

    Why acid base reaction is not preferred here in basic hydrolysis?

    How is it possible that leaving group of NH3 is not protoneted by excess of strong acid? Why not H2O is taking the proton from molecule after leaving the NH3 group?

    Oh, God! Why doesn't sodium ion from sodium hydroxide react with a carboxylic acid ion? It would make no sense to protonate it at that rate.

    I don't get it. Why does NH2 leave? NH2 is a very bad leaving group...? Why do we have to make here an exception?

    • @des6309
      @des6309 8 ปีที่แล้ว

      that's why you heat it, and you add proton to make it a good leaving group.plus, amides are more reactive than carboxylic acids
