Nonclassical ion

Index Nonclassical ion

Nonclassical carbocations are stabilized by charge delocalization from contributions of neighbouring C-C or C-H bonds, which can form bridged intermediates or transition states. [1]

11 relations: Anti-periplanar, Carbocation, Delocalized electron, Epimer, Hexafluoro-2-propanol, Neighbouring group participation, Nucleophilic substitution, Solvation, Solvolysis, Steric effects, 2-Norbornyl cation.

Anti-periplanar

Anti-periplanar is a term used in organic chemistry to describe the A–B–C–D bond angle in a molecule.

Delocalized electron

In chemistry, delocalized electrons are electrons in a molecule, ion or solid metal that are not associated with a single atom or a covalent bond.

Epimer

In stereochemistry, an epimer is one of a pair of stereoisomers.

Hexafluoro-2-propanol

Hexafluoroisopropanol, commonly abbreviated HFIP, is the organic compound with the formula (CF3)2CHOH.

Neighbouring group participation

Neighbouring group participation (NGP) (also known as anchimeric assistance) in organic chemistry has been defined by IUPAC as the interaction of a reaction centre with a lone pair of electrons in an atom or the electrons present in a sigma bond or pi bond contained within the parent molecule but not conjugated with the reaction centre.

Nucleophilic substitution

In organic and inorganic chemistry, nucleophilic substitution is a fundamental class of reactions in which an electron rich nucleophile selectively bonds with or attacks the positive or partially positive charge of an atom or a group of atoms to replace a leaving group; the positive or partially positive atom is referred to as an electrophile.

Solvation

Solvation describes the interaction of solvent with dissolved molecules.

Solvolysis

Solvolysis is a type of nucleophilic substitution (SN1) /(SN2) or elimination, where the nucleophile is a solvent molecule.

Steric effects

Steric effects are nonbonding interactions that influence the shape (conformation) and reactivity of ions and molecules.

2-Norbornyl cation

In organic chemistry, the term 2-norbornyl cation (equivalent with 2-bicyclo-heptyl cation) describes one of the three carbocations formed from derivatives of norbornane.
