Ligands play an important role in the formation of complex salts. Complex salts are compounds that consist of a central metal atom or ion surrounded by ions or molecules called ligands. Ligands are responsible for coordinating with the central metal atom or ion through coordinate bonds.
Let's analyze each option given in the question to understand why option 'D' is the correct answer:
a) Anions linked by coordinate bonds to a central metal atom or ion:
This option suggests that anions are the ligands in a complex salt. However, ligands can be either ions or molecules, and they can be positively charged (cations) or negatively charged (anions). Therefore, this option is incorrect.
b) Cations linked by coordinate bonds to a central metal or ion:
This option suggests that cations are the ligands in a complex salt. Although cations can form coordinate bonds with a central metal atom or ion, they do not act as ligands in complex salts. Ligands are typically neutral or negatively charged species. Therefore, this option is incorrect.
c) Molecules linked by coordinate bonds to a central metal or ion:
This option correctly identifies that molecules can act as ligands in a complex salt. Ligands can be neutral molecules that coordinate with the central metal atom or ion through coordinate bonds. However, this option does not consider the possibility of ions acting as ligands. Therefore, this option is incomplete and not the correct answer.
d) Ions or molecules linked by coordinate bonds to a central atom or ion:
This option encompasses the complete definition of ligands in complex salts. Ligands can be either ions or molecules that coordinate with the central metal atom or ion through coordinate bonds. This option includes all the possibilities and is the correct answer.
In conclusion, option 'D' is the correct answer because it accurately describes the nature of ligands in complex salts. Ligands can be ions or molecules that coordinate with a central metal atom or ion through coordinate bonds.
