[PDF] acid base hydrolysis of amides

Hydrolysis of an amide in acid solution actually gives a carboxylic acid and the salt of ammonia or an amine (the ammonia or amine initially formed is neutralized by the acid). Basic hydrolysis gives a salt of the carboxylic acid and ammonia or an amine.

  • What is the acid base reaction of amides?

    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 amide hydrolysis be catalysed by acid or base?

    The acid acts as a catalyst for the reaction between the amide and water. The alkaline hydrolysis of amides actually involves reaction with hydroxide ions, but the result is similar enough that it is still classed as hydrolysis.

  • Does amide react with Naoh?

    Amides can also be hydrolyzed under basic conditions, such as with sodium hydroxide, to give carboxylate salts and ammonia. This is just like in the acid case, often forcing conditions are required such as high temperatures.
  • The hydrolysis of acetamide was followed by ailalyziilg for the acetic acid produced. About 5 in1 of reaction solutioil (initially either 0.2992 M in perchloric acid and 0.1980 A6 in acetaillide or 3.99 M in perchloric acid and 0.0990 A6 in acetamide) were withdrawn and 3.00 in1 pipetted into a 30-ml weighing bottle.
