A nucleophile provides a pair of electrons to form a new covalent bond. It can be also seen as a Broensted base. Stronger the base (higher pKa for the acid/base couple), stronger the nucleophile, e.g. this series of nucleophilicity ^â€“NH₂ > HO^- > F^-, but it not true for this series Cl^- > F^- or HS^- > HO^-.

In an acid/base couple, the base is always a stronger nucleophile.

For strong bases/nucleophiles, pKa>14.

An electrophile accepts a pair of electrons to form a new covalent bond. It canâ€™t be identified as Broensted acid or base.
