Nucleophile (nucleophilic reagent)

亲核试剂(亲核体)

Explanation (EN)

A nucleophile (nucleophilic reagent) is an electron-pair donor, that is, a Lewis base, that is attracted to a nucleus or a positive (electron-poor) centre. The word means 'nucleus-loving', reflecting this attraction. Nucleophiles attack electrophiles, donating an electron pair to form a new bond.

Explanation (ZH)
