Good morning mate !

Here's your answer :

Ambident nucleophiles are those with 2 nucleophile centres. For example cyanide act as ambident nucleophile.

There are 2 nucleophile centres, at carbon and nitrogen in cyanide ion (C=N:). They can react through either of these centres. Depending on the reagent and the reaction conditions, the reaction may take place predominantly at one of these centres.  

Examples are C = N: (reagent KCN, NaCN) etc.
