Nucleophiles which can attack through two different sites are known as ampident nucleophiles

1Thank You

Yogita Ingle 7 years, 4 months ago

The nucleophiles which has two different electron donor atoms and can attack through two different sites are called ambident nucleophiles.
For example : Cyanide ion (CN) has two resonating structures :
C≡N
C=N
So, it can attack through carbon to form cyanides and through N to form isocyanides or carbylamines.
