Question

Which of the following is an ambident nucleophile :- (A) HSO3 ominus (B) CN ominus (C) NO2 ominus (D) All of these

Tardigrade Admin · Accepted Answer

Ambident nucleophile are the nucleophile those have more than one atom to donate electron to reactant. In CN-,C &N these two atoms donate electron. In NO2-,N &O these two atoms donate electron. In HSO3-,S &O these two atoms donate electron. So all of these are ambident ligand.

Ambident nucleophile are the nucleophile those have more than one atom to donate electron to reactant. In CN−,C&N these two atoms donate electron. In NO2−​,N&O these two atoms donate electron. In HSO3−​,S&O these two atoms donate electron. So all of these are ambident ligand.

$H S O_{3}^{⊖}$

$CN ⊖$

$N O_{2} ⊖$
