nucleophile

listen to the pronunciation of nucleophile
English - Turkish
nükleofil
English - English
a compound or functional group that is attractive to centres of positive charge, and donates electrons, especially donating an electron pair to an electrophile to form a bond
a species that loves a nucleus Since nuclei are positively charged, nucleophiles are negatively charged or bear a partial negative charge Examples are lone pairs or a hydroxide ion
From the Greek, meaning nucleus loving A molecule or ion that donates a pair of electrons to another atom or ion to form a new covalent bond; a Lewis base
Atom or molecule that contains an electron pair available for bonding and in chemical reactions therefore seeks a positive centre, such as the nucleus of an atom or the positive end of a polar molecule (see covalent bond; electric dipole). In the Lewis electron theory (see acid-base theory), advanced by the U.S. chemist Gilbert Lewis (1875-1946) in 1923, nucleophiles are by definition Lewis bases. Examples include the hydroxide ion (OH^-), the ions of the halogens chlorine, bromine, and iodine (Cl^-, Br^-, and I^-, respectively), ammonia (NH3), and water (H2O). See also base; electrophile
A chemical reagent that reacts by forming covalent bonds with electronegative atoms and compounds
Literally, something that loves nuclei All nucleophiles are Lewis bases
