`CN^(-)andNO_(2)^(-)` are called ambident nucleophiles. Explain

Explanation

Nucleophiles which have more than one (generally two suitable atoms through which they can attack the substrate are called ambident nucleophiles. Each of the ions `overset(Theta)(C )N and NO_(2)^(Theta)` contain two atoms through which they can be involved in nueleophilic attack (these atoms are indicated by arrowos). So these are ambident nucleophiles.
`[:overset(Theta)underset(uarr)(C)-=N:harr:C=overset(* *Theta)underset(uarr)(N):]`
