In the case of N-unsubstituted imidazoles and pyrazoles, complexation of the pyridine-like nitrogen causes a considerable increase in the acidity of the pyrrolelike nitrogen.doi:10.1016/S0065-2725(08)60162-2Javier CatalanJose Luis M. Abboud...
It turns out that the nitrogen in pyrrole is unusually non-basic. In fact, even when subjected to acid, pyrrole reacts at carbon (C-2), and not on the nitrogen. Pyridine [pKaH = 5.2] is far more basic than pyrrole [pKaH about –3.6 ] Why? Draw the conjugate acid of pyrrole. No...
Rank the following compounds in terms of increasing A) acidity: CH3OH, HCl, NH3, and CH4 B) basicity: CH3O-, H2N-, H2O, and NH3 Rank the compound in the given group in order of increasing reactivity toward nucleophilic attack. Rank the given acids in order of increasing strength...
Results obtained from carbon monoxide, carbon dioxide, sulfur dioxide, pyrrole, chloroform, acetonitrile, alcohols, thiols, boric acid trimethyl ether, ammonia and pyridine are critically reviewed. It is concluded that no probe can be universally used. Pyrrole in the case of alkaline zeolites, CO ...
