Chemistry:Migratory aptitude

From HandWiki

Migratory aptitude is the relative ability of a migrating group to migrate in a rearrangement reaction.[1] Migratory aptitudes vary in different reactions, depending on multiple factors.[2] In the Baeyer-Villiger reaction, the more substituted group, in general, migrates.[3] In the pinacol rearrangement, the order of migratory aptitude has not been determined unambiguously,[2] but some trends have been determined. For example, relative migratory aptitudes for alkyl substituents is Hydride >Phenide>C(CH3)3> C2H5 > CH3.[2] More bulky groups have more tendency to migrate.
