What are ambident nucleophiles

Ambident nucleophile are those nucleophilies which have two bonding sites .example- kcn, no2

Electron rich species which contain more than one donar atom but only one type of atom donate electron at a time is known as ambident nucleophile.

Nucleophiles are basically a group of atoms, molecules, compounds which can donate PAIR of electrons to form coordination covalent bonds for example halogen ions(except fluoride ion), sulphate ion, any negatively charged ion, NH3, etc... Ambident nucleophiles a.k.a. ambidentate (ambident) ligands are the nucleophiles (eletron PAIR donors) which have two donor sites from where they can donate electrons and form coordinate bond condition given that they form ONLY one bond at a single time. For example cynide ion can form only one bond at a time but can form the bond from two different donor st=pots i.e., from carbon as well as from nitrogen, same for thiocynide ion which can again from only one bond at a time but from two different donor sites cabon and nitrogen, also nito group and many more....

Which have two donor sites nd both donar sites behaves different from each ohter is kn as ambient nucleophile

Which have two doner atom .Like Cyanide ion
