A sigmatropic rearrangement is defined as migration, in an uncatalyzed intramolecular process, of a σ bond, adjacent to one or more π systems, to a new position in a molecule, with the π systems becoming reorganized in the process. Examples are The order of a sigmatropic rearrangement is expressed by two numbers set in brackets: …

What is hydrogen bond with examples? The hydrogen atom which is bonded to an electronegative atom can form a hydrogen bond to a second electronegative atom. It is thus a force of attraction between opposite partial charges δ+ charge on H in the OH group and δ– charge on the O of another group. Hydrogen bond requires …

Resonance or Mesomerism: The concept of resonance in organic chemistry owes its origin primarily to the fact that isomers of ortho-substituted derivatives of benzene do not exist. Further, benzene is found to be resistant, unlike ethylenic compounds to addition reactions, although its classical structures show three double bonds. To explain the limitations of these classical structures …
