The set with only ambidentate ligands in the following is

1. $\mathrm{NO}_3{ }^{\ominus}, \mathrm{Br}^{\ominus}, \mathrm{C}_2 \mathrm{O}_4^{2 \ominus}$
2. $\mathrm{NO}_2^{\ominus}, \mathrm{CN}^{\ominus}, \mathrm{SCN}^{\ominus}$
3. $\mathrm{NO}_2^{\ominus}, \mathrm{C}_2 \mathrm{O}_4^{2 \ominus}, \mathrm{NH}_3$
4. $\mathrm{SCN}^{\ominus}, \mathrm{CO}, \mathrm{NH}_3$

Solution

The ligands containing two donor sites but use only one at a time are known as ambidentate ligand
