[PDF] amide hydrolysis in acid

Acid Catalysed Amide Hydrolysis In an acidic medium, amide interacts with the water molecule to give a carboxylic acid and the salt of ammonia or amine salt. We will activate the amide since we only have a weak nucleophile and a poor electrophile. Protonation of the amide carbonyl makes it more electrophilic.

  • Can acetamide hydrolysis with HCL?

    Hydrolysis of Amides
    If acetamide is heated with a dilute acid (such as dilute hydrochloric acid), acetic acid is formed together with ammonium ions.
    So, if you were using hydrochloric acid, the final solution would contain ammonium chloride and acetic acid.

  • Can amides react with acids?

    Amides can be hydrolyzed into a carboxylic acid and ammonia or an amine by heating in an acidic or basic aqueous solution.
    In both cases, acid-base reactions occurring with the products make the overall reaction irreversible.

  • Can amides be hydrolyzed in acidic and basic conditions?

    This page describes the hydrolysis of amides under both acidic and alkaline conditions.
    It also describes the use of alkaline hydrolysis in testing for amides.
    What is hydrolysis? Technically, hydrolysis is a reaction with water.

  • Can amides be hydrolyzed in acidic and basic conditions?

    Acidic hydrolysis is simply the reverse of esterification.
    The ester is heated with a large excess of water containing a strong-acid catalyst.
    Like esterification, the reaction is reversible and does not go to completion.
