 Imidazole has a pKa = 7 with respect to its conjugate acid. Which N is protonated in this conjugate acid and why?
  • a)
     N1 because imidazole is an aromatic heterocycle where n = 1 as per Huckel’s rule.
  • b)
     N1 is protonated because it is sp3 hybridized.
  • c)
     N3 is protonated because it is sp2 hybridized.
     
  • d)
    N1 is protonated because the lone pair is part of the aromatic pi system
     
Correct answer is option 'C'. Can you explain this answer?
Most Upvoted Answer
Imidazole has a pKa = 7 with respect to its conjugate acid. Which N is...
The lone pair of N1 are participating in aromaticity so they are not available to donate
& lone pair of N5 are free to donate so N5 will be protonated
