Substitution reaction in octahedral complexes
Web14 Sep 2024 · The stereochemical consequences of substitution of octahedral complexes are much more intricate than those of square-planar complexes. The cis complexes do not undergo isomerization when substitution occurs, whereas the trans forms show a tendency to isomerize in the order Y = NO 2– < Cl – < NCS – < OH – . WebSubstitution reactions in organic chemistry are classified either as electrophilic or nucleophilic depending upon the reagent involved, whether a reactive intermediate involved in the reaction is a carbocation, a carbanion or a free radical, and whether the substrate is aliphatic or aromatic.
