Nucleophile Definition

2016-09-30 12:52:51 · answer #2 · answered by ? 4 · 0 0

a nucleophile is a molecule which attacks on +vely charged atom of a substrate.
substitution rcn in which one atom is replaced by another which iis of the reagent .

when nucleophile replace an atom of a substrate then in such a rcn a -ve charged atom is released and this rcn is called nuclephilic substitution rcn.

eg. CH3Cl + aq KOH ---> CH3OH + Cl negative
here the nucleophile is OH negative

THIS RCN IS NUCLEOPHILIC SUBSTITUTION .

There is a substition on the most postive part of the molecule. A nucleophile will seek out the positive center, bond with it and then the part that was previosly bonded to that positive center will be released.

In chemistry, an electrophile (literally electron-lover) is a reagent attracted to electrons that participates in a chemical reaction by accepting an electron pair in order to bond to a nucleophile. Because electrophiles accepts electrons, they are Lewis acids (see acid-base reaction theories). Most electrophiles are positively charged. In chemistry, a nucleophile (literally nucleus lover) is a reagent which is attracted to centres of positive charge. A nucleophile participates in a chemical reaction by donating electrons to a species known as an electrophile in order to form a chemical bond. Because nucleophiles donate electrons, they are by definition Lewis bases (see acid-base reaction theories). ... In Organic chemistry, a radical substitution reaction is a substitution reaction involving free radicals as a reactive intermediate.
