The term “rearrangement” is used to describe two different types of organic chemical reactions. A rearrangement may involve the one -step migration of an H atom or of a larger molecular fragment within a relatively short lived intermediate. On the other hand, a rearrangement may be a multi-step reaction that includes the migration of an H ...

Oct 17, 2011 · Introduction to Rearrangement Reactions. Reactions that involve a carbocation intermediate may be accompanied by rearrangements where a pair of electrons from a C-H or C-C bond migrates toward the carbocation, resulting in breakage and formation of a C-H or C-C bond, and formation of a new carbocation. The new carbocation (generally more stable ...
Benzilic Acid Rearrangement. The benzilic acid rearrangement involves conversion of a 1,2-diketone into a carboxylic acid. The conditions are deceptively simple, hydroxide followed by an acid quench, and lead to the migration of a benzene ring. This mechanism is relatively straightforward.
Organic Rearrangement Reactions refer to the vast class of chemical reactions which deal with chemical reactions whereby there is a change in the carbon structure of the molecule to make way for the isomer structure of the original molecule. It might be a single step reaction where there occurs the migration of the Hydrogen or H atom.

What happens when a carbocation intermediate is accompanied by a rearrangement reaction?
Definition. Rearrangements are a class of organic reactions where the atoms in a molecule are reorganized, leading to the formation of a new compound with a different structure. This term is particularly relevant in the context of polar reaction mechanisms and the preparation of alkyl halides from alkanes through radical halogenation.
