Definitions:

Nucleophile

An entity in chemistry that transfers a pair of electrons to an electrophile, enabling the formation of a chemical bond as a part of the reaction process.

Lewis Definition

A theory of acids and bases where acids accept a pair of electrons during a reaction, while bases donate a pair of electrons.

Acids

Substances that donate protons (hydrogen ions) in aqueous solutions and can react with bases to form salts, often characterized by a sour taste.

Electrophile

A reactive species that seeks out electrons, often forming a bond by accepting an electron pair from a nucleophile.
