Clar's rule. In organic and physical organic chemistry, Clar's rule is an empirical rule that relates the chemical stability of a molecule with its aromaticity. It was introduced in 1972 by the Austrian organic chemist Erich Clar in his book The Aromatic Sextet. The rule states that given a polycyclic aromatic hydrocarbon, the resonance ...
Arrow pushing or electron pushing is a technique used to describe the progression of organic chemistry reaction mechanisms. [ 1] It was first developed by Sir Robert Robinson. In using arrow pushing, "curved arrows" or "curly arrows" are drawn on the structural formulae of reactants in a chemical equation to show the reaction mechanism.

Baldwin's rules in organic chemistry are a series of guidelines outlining the relative favorabilities of ring closure reactions in alicyclic compounds. They were first proposed by Jack Baldwin in 1976. [1] [2] Baldwin's rules discuss the relative rates of ring closures of these various types.
Organic derivatives of the less electropositive main group elements are often robust. Like their derivatives lacking organic substituents, halides and alkoxide ligands for the later organomain group compounds tend to hydrolyze. Organophosphorus and silanes exhibit this pattern: R 3 SiCl + H 2 O → R 3 SiOH + HCl R 2 PCl + H 2 O → R 2 POH + HCl
IUPAC nomenclature of organic chemistry. In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended [ 1][ 2] by the International Union of Pure and Applied Chemistry (IUPAC). It is published in the Nomenclature of Organic Chemistry (informally called the Blue Book ).
Category. v. t. e. Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. [ 1] Study of structure determines their structural formula.
In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions. The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition. [ 1][ 2] This enables systematic prediction of chemical reactions and ...
