Question
Chapter 23, Problem 23.68AP
Interpretation Introduction
Interpretation:
The different splitting pattern at different
Concept Introduction:
In the NMR spectroscopy the resonance energy of the proton is observed. The splitting in the peak takes place because of the interaction of proton with neighbouring proton. The change in the surroundings of proton produces different splitting patterns.

- 16-27 Guanidine, p/Ca 13.6, is a very strong base, almost as basic as hydroxide ion. NH NH2+ II II H2N—C—NH2 + H2O H2N—C—NH2 + OH" Guanidine Guanidinium ion pKb = 13.6 Complete the Lewis structure for guanidine, showing all valence electrons. The remarkable basicity of guanidine is attributed to the fact that the positive charge on the guanidinium ion is delocalized by resonance over the three nitrogen atoms. This delocalization increases the stability of the guanidinium ion relative to the ammonium ion or substituted ammonium ions. Draw three equivalent contributing structures for the guanidinium ion and show by the use of curved arrows how these three contributors are related. Propose an explanation for the fact that protonation occurs on the C=NH nitrogen rather than on one of the —NH., nitrogens.
