Question:

Which of the following are ambident nucleophiles? 
[A.] CN$^{\,-}$ 
[B.] CH$_{3}$COO$^{\,-}$ 
[C.] NO$_{2}^{\,-}$ 
[D.] CH$_{3}$O$^{\,-}$ 
[E.] NH$_{3}$

Show Hint

Ambident nucleophiles can attack from two different atoms, making them more versatile in reactions compared to single-atom nucleophiles.

The Correct Option is B

Solution and Explanation

Understanding ambident nucleophiles: Ambident nucleophiles are molecules that can donate electrons from two different atoms.
Option A (CN-) is an ambident nucleophile because it can donate electrons from the carbon or nitrogen atom.
Option C (NO2-) is an ambident nucleophile because it can donate electrons either from the nitrogen or the oxygen atom.
Option B (CH3COO-), Option D (CH3O-), and Option E (NH3) are not ambident nucleophiles.
Thus, the correct answer is option (2).
