Q. Which of the following ligand gives chelate complexes?

NTA AbhyasNTA Abhyas 2022

Solution:

$C_{2}O_{4}^{2 -}$ is a symmetrical bidentate ligand so it can be used for chelate complex formation.
Pyridine, $NH_{2}-\overset{+}{N}H_{3}$ are monodentate ligands so can not form chelate complex.
$SCN^{-}$ is an ambidentate ligand so only one site can be used at a time so no chelate complex is possible.
