Migratory aptitude

Migratory aptitude

Migratory aptitude is the relative ability of a migrating group to migrate in a rearrangement reaction. This can be affected by the leaving group (whichever gives a more stable carbocation) and the group that 'stays' (whichever can stabilize the positive charge best).It also depends upon the electron density of the migrating group i.e. Hydride > tert-alkyl > sec-alkyl = phenyl > primary alkyl > methyl>H

The Migratory aptitude is used in reactions such as Pinacol-PINACOLONE rearrangements, etc...........
