Write one example of each:
(i) a nucleophile, (ii) an electrophile.

Solution

All molecules or ions with a free pair of electrons or at least one pi bond can act as nucleophiles. Because nucleophiles donate electrons, they are by definition Lewis bases. For example Cynaide ion CN^- or Hydroxyl ion OH^- are nucleophilies.

Electrophiles are positively charged or neutral species having vacant orbitals that are attracted to an electron rich centre. It participates in a chemical reaction by accepting an electron pair in order to bond to a nucleophile. Because electrophiles accept electrons, they are Lewis acids. For example mercury cation Hg⁺.
