Τι (ποιος) είναι nucléophile - ορισμός

CHEMICAL SPECIES THAT DONATES AN ELECTRON PAIR TO FORM A CHEMICAL BOND IN RELATION TO A REACTION

Nucleophilicity; Nucleophiles; Nucleophilic; Nucleophilic attack; Ambident nucleophile; Nucleophyl

Nucleophile

In chemistry, a nucleophile is a chemical species that forms bonds by donating an electron pair. All molecules and ions with a free pair of electrons or at least one pi bond can act as nucleophiles.

nucleophilic

[?nju:kl??(?)'f?l?k]

¦ adjective Chemistry having a tendency to donate electrons or react with protons. Often contrasted with electrophilic.

Derivatives

nucleophile noun

Carbanion

ANION WITH AN EVEN NUMBER OF ELECTRONS AND HAVING AN UNSHARED PAIR OF ELECTRONS ON A TERVALENT CARBON ATOM OR—IF THE ION IS MESOMERIC—HAVING AT LEAST ONE SIGNIFICANT CONTRIBUTING STRUCTURE WITH AN UNSHARED PAIR OF ELECTRONS ON A TERVALENT CARBON ATOM

Active hydrogen compound; Carbon nucleophile; Carbon acid; CH acidity; Carbanions

A carbanion is an anion in which carbon is trivalent (forms three bonds) and bears a formal negative charge (in at least one significant resonance form).

Nucleophile

In chemistry, a nucleophile is a chemical species that forms bonds by donating an electron pair. All molecules and ions with a free pair of electrons or at least one pi bond can act as nucleophiles. Because nucleophiles donate electrons, they are Lewis bases.

Nucleophilic describes the affinity of a nucleophile to bond with positively charged atomic nuclei. Nucleophilicity, sometimes referred to as nucleophile strength, refers to a substance's nucleophilic character and is often used to compare the affinity of atoms. Neutral nucleophilic reactions with solvents such as alcohols and water are named solvolysis. Nucleophiles may take part in nucleophilic substitution, whereby a nucleophile becomes attracted to a full or partial positive charge, and nucleophilic addition. Nucleophilicity is closely related to basicity.
