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.

Jun 5, 2012 · A nucleophile is a reactant that donates a pair of electrons to form a new covalent bond. An electrophile is a reactant that accepts a pair of electrons.

nucleophile, in chemistry, an atom or molecule that in chemical reaction seeks a positive centre, such as the nucleus of an atom, because the nucleophile contains an electron pair available for bonding.

A nucleophile is a reagent consisting of an atom, ion, or molecule that donates electron pair to form a bond. It is an electron-rich species that can be negatively charged or neutral with available electrons.

The thiol group in a cysteine amino acid, for example, is a powerful nucleophile and often acts as a nucleophile in enzymatic reactions, and of course negatively-charged thiolates (RS -) are even more …

Jun 6, 2025 · At its core, a nucleophile (from the Greek nucleus ‘kernel’ and philos ‘loving’) is a chemical species that donates an electron pair to form a chemical bond.

Nucleophile (Nuc): A reactant that provides a pair of electrons to form a new covalent bond (i.e. a Lewis base). A nucleophile that shares an electron pair with a proton is usually called a Bronsted-Lowry …

A nucleophile, which means "nucleus-loving," is a chemical species that donates an electron pair to an electron-deficient centre (an electrophile) to form a new covalent bond.

A nucleophile (or nucleophilic reagent) is a reagent that forms a bond to its reaction partner (the electrophile) by donating both bonding electrons. A 'nucleophilic substitution reaction ' is a heterolytic …

A nucleophile is an electron-rich molecule that can form covalent bonds by donating electrons to electron-poor sites. Many molecules can act as a nucleophile in a chemical reaction, though some …
