(i) The protonic definition cannot be used to explain the reactions occuring in non-protonic solvents such as COCl2, SO2, N2O4, etc.
(ii) It cannot explain the reactions between acidic oxides like etc and the basic oxides like etc which take place even in the absence of the solvent e.g.,
There is no proton transfer in the above example.
(iii) Substances like BF3, AlCl3 etc, do not have any hydrogen and hence cannot give a proton but are known to behave as acids.

Thanks a lot but I didn't found the example

Answer:
Limitation of Bronsted Lowey concept:
It doesn't describe the acidic and basic nature of organic compound. ... According to Bronsted Lowery conceptsame compound in one reaction act asacid and another reaction act as baseso, it is difficult to predict the exactacid or base.
