Why are Imides acidic?
Why are Imides acidic?
The N–H center for imides derived from ammonia is acidic and can participate in hydrogen bonding. Unlike the structurally related acid anhydrides, they resist hydrolysis and some can even be recrystallized from boiling water.
Is imide acidic or basic?
As expected, imides are more acidic and less basic than amides as suggested by the resonance structures in Fig. 1-iii.

What are imides in organic chemistry?
In organic chemistry, an imide is a functional group consisting of two acyl groups bound to nitrogen. The compounds are structurally related to acid anhydrides, although imides are more resistant toward hydrolysis. In terms of commercial applications, imides are best known as components of high-strength polymers, called polyimides.
What is the difference between amide and imide?
Not to be confused with Amide or Imine. In organic chemistry, an imide is a functional group consisting of two acyl groups bound to nitrogen. The compounds are structurally related to acid anhydrides, although imides are more resistant toward hydrolysis.
