The Correct Option is D

Solution and Explanation

MLM - L bond is coordinate. In ligand itself, NH3NH_{3}, three hydrogens are covalently linked to nitrogen atoms. Hence, total number of covalent bonds=6×3=18= 6 \times 3 = 18

Concepts Used:

Coordination Compounds

A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.

Coordination entity:

A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.

Ligands:

A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
