Ambident nucleophiles are species that can donate electrons from multiple different atoms to form bonds with electrophiles. Common examples include enolate ions, nitrite ions, and the cyanide ion. These species exhibit different reactivity depending on which atom is involved in the nucleophilic attack.
Yes, cyanide is considered an ambident ligand because it can coordinate through the carbon or the nitrogen atom, depending on the metal center.
The given reaction is:The given reaction is an SN2 reaction. In this reaction, CN−acts as the nucleophile and attacks the carbon atom to which Br is attached. CN−ion is an ambident nucleophile and can attack through both C and N. In this case, it attacks through the C-atom.
Yes, cyanide is considered an ambident ligand because it can coordinate through the carbon or the nitrogen atom, depending on the metal center.
Nucleophiles which can attack through two different sites are called ambident nucleophiles. For example, cyanide ion is a resonance hybrid for its structure. It can attack either through carbon to form cyanides or through N to form isocyanides or carbylamines.

KCN + RCl ------------>RCN + KCl : this is in aqueous medium. here K+ ions displace the less electropositive R+ ions and hence the rxn is a simple rxn of alkyl halides. AgCN + RCL --------------> R=N-->C + AgCl : but this rxn is in alcoholic medium. N & C ions can both donate a lone pair of electrons. such groups are called ambident nucleophile
