Question
Chapter 19, Problem 36P
Interpretation Introduction
Interpretation:
The reason for pyrrole being much stronger acid than ammonia has to be explained.
Concept Introduction:
Pyrrole is a cyclic compound contains two pi bonds between carbon atom and nitrogen atom is present at adjacent position to both double bonds which favors delocalization of electrons and in ammonia no delocalization of electrons takes place due to absence of pi bonds.
