$IV > I > II > III$

Vedclass · Answer

(C) The basicity of a compound depends on the stability of its conjugate acid. More stable conjugate acid means a more basic compound.$IV$ (Guanidine) is the most basic because its conjugate acid is stabilized by resonance with three equivalent canonical forms.$I$ (Acetamidine) is the next most basic as its conjugate acid is stabilized by resonance with two equivalent canonical forms.$II$ ($2$-Imidazoline) is more basic than $III$ (Imidazole) because the lone pair in $II$ is in an $sp^3$ hybridized orbital,whereas in $III$,the lone pair is part of the aromatic sextet and is less available for protonation.Thus,the order of basicity is $IV > I > II > III$.

The order of basicity among the following compounds is:
