Solution
Nucleophile:
It's a chemical species that form bonds by giving another chemical species an electron pair. Nucleophiles are molecules and ions that have at least one pi bond and have a free pair of electrons
Because nucleophiles share electrons, they are referred to as Lewis bases.
Nucleophiles can take part in nucleophilic substitution and addition, in which a nucleophile attracts a full or partial positive charge.
Nucleophilic reagents replace a molecule's leaving group and offer a pair of electrons for the creation of a new bond.
Anions, such as, or compounds with a lone pair of electrons, such as, are examples of nucleophiles.
Therefore, Nucleophiles are reagents that bring an electron pair.
