What is the mechanism of amide hydrolysis?
Mechanism: In base catalysed amide hydrolysis, the amide is heated with boiling aqueous NaOH or KOH.
The nucleophilic hydroxide ion adds to the carbonyl carbon to form a tetrahedral intermediate.
Proton attacks the NR2 group.
What is the mechanism of formation of amides?
The addition of ammonia (NH₃) to a carboxylic acid forms an amide, but the reaction is very slow in the laboratory at room temperature.
Water molecules are split out, and a bond is formed between the nitrogen atom and the carbonyl carbon atom.
In living cells, amide formation is catalyzed by enzymes.
One of the most common methods to make an amide is to take a carboxylic acid and convert it to an acid chloride by using thionyl chloride (SOCl2).

What is the method of synthesis of amides?

Simple amides can be prepared by reacting an acid anhydride with an amine.
Lastly, amides can be formed through the direct reaction of a carboxylic acid and an amine.
However, this reaction is rarely used because the conditions are relatively severe.
