Interpretation: The stronger basic character of guanidine compared to other amines has to be found
Concept Introduction:
Resonance is a mental exercise and method within the Valence Bond Theory of bonding that describes the delocalization of electrons within molecules. The net sum of valid resonance structures is defined as a resonance hybrid, which represents the overall delocalization of electrons within the molecule. A molecule that has several resonance structures is more stable than one with fewer. If a compound has high resonance structures and the lone pair on any other atom is delocalized, then that compound is less basic. If a compound has no resonance structures and the lone pair on any other atom is localized, then that compound is more basic.
To find: Explain the stronger basic character of guanidine compared to other amines
Find the nitrogen atom which is protonated easily in guanidine
