nucleophile noun

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 substitution

CLASS OF CHEMICAL REACTIONS IN WHICH A LEAVING GROUP(ELECTROPHILE) IS REPLACED BY AN ELECTRON RICH COMPOUND(NUCLEOPHILE).

Nucleophilic substitution reaction; Nucleophilic Substitution; Nucleophilic aliphatic Substitution; Sn reactions; SN Reactions; Nucleophilic aliphatic substitution; SN reaction; Nucleophilic displacement; Intramolecular nucleophilic substitution

In chemistry, a nucleophilic substitution is a class of chemical reactions in which an electron-rich chemical species (known as a nucleophile) replaces a functional group within another electron-deficient molecule (known as the electrophile). The molecule that contains the electrophile and the leaving functional group is called the substrate.

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.
