Question

which of the following can function as a chelating agent? a. Sh- b. H2O c. H2 NCH2CO2- D. SCN-​

Answer 1

Answer:

Explanation:

Mainly atoms like S, N and O function as atoms in the form of chemical groups like –SH, –S-S, –NH2, =NH, –OH, –OPO3H, or >C=O.

Answer 2

Option (C) - $H2 NCH2CO2-$  can function as a chelating agent

Explanation:

• The substances in which the molecules can form multiple bonds with a single metal ion.

• They are also known as the chelating agents.

• It is a multidentate ligands.

• Examples of chelating agents include Oxalato, glycinato and ethylene diamine.
• $-SH, -S-S, -NH2, =NH, -OH, -OPO3H, or > C=O.$ are few examples of chelating agent.
• They are ligands which can form rings as they all are bidentate ligands. Hence they all are also chelating ligands.
