pKa of Ac2N-H : 17,9
pKa of succinimide : 14,7

An azimine is an azo imide.
An amine imide is any of a class of organic compounds formally derived from an amine and a nitrene - R3N+-N-R.
HCl is an acid, so it does not possess basicity but rather acidity. Its basicity is 0.
The Global Polyamide-imide Resin Market growing at a CAGR of 6.2%, and it is expected to reach USD 0.91 billion by 2029, over the forecast period 2023-2029.
Measuring the pH it is possible to evaluate the basicity of a solution.
if basicity increases,fluidity decreases
Basicity of a compound is usually determined by counting the number of basic sites (nitrogen or oxygen atoms capable of accepting a proton) present in the molecule. For amines, the basicity increases with the number of alkyl groups attached to the nitrogen atom. For acids, basicity is based on the ionizable hydrogen atoms present. pKa values represent the acidity of the compound, inversely related to basicity.

If a proton on N between two C=O's is removed by a base, one can draw two resonance structures, one involving each C=O, to stabilize the resulting anion. However, with an amide, there is only one C=O and when the H is removed, only one resonance structure can be drawn. As a result, the amide H is less acidic than the imide H.
I think , the basicity of sulphuric acid is 1.
it is acidic.
The basicity of imidazole is influenced by its structure. Imidazole has a nitrogen atom in its ring structure that can easily accept a proton, making it a weak base. The presence of this nitrogen atom contributes to imidazole's basicity.
