Guanidine is a stronger base than the typical amine. The increased basicity can be explained by drawing the resonance structures of the protonated guanidine. The protonated guanidine $$(A)$$ has been drawn for you. Draw major resonance structures, $$\mathbf{B}$$ and $$\mathbf{C}$$, and one minor resonance structure, $$\mathbf{D}$$. Be sure to include the formal charge, lone pairs, and hydrogens on nitrogen for structures B, C, and D. Draw structure B.
