Question

Name the term used for a reagent that brings an electron pair.

Answer 1

Nucleophile:

1. 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
2. Because nucleophiles share electrons, they are referred to as Lewis bases.
3. Nucleophiles can take part in nucleophilic substitution and addition, in which a nucleophile attracts a full or partial positive charge.
4. Nucleophilic reagents replace a molecule's leaving group and offer a pair of electrons for the creation of a new bond.
5. Anions, such as${\mathrm{Cl}}^{-}$, or compounds with a lone pair of electrons, such as${\mathrm{NH}}_3$, ${\mathrm{PR}}_3$are examples of nucleophiles.

Therefore, Nucleophiles are reagents that bring an electron pair.
