Pyrazole and Indazole on protonation of nitrogen at position 3 yields pyrazolium cation and indazolium cation respectively without losing their aromaticity. Phenyl group in indazole contributes larger number of resonance structures (scheme 2) makes the indazolium cation more stable than the pyrazolium cation with a smaller number of resonance structures (scheme 1). This makes the indazolium cation less susceptible toward substituent effect on the deprotonation equilibrium. Also, the present article is a good chemical education exercise to undergraduate students for writing the resonance structures of pyrazolium cation.
