Explanation Reason for correct option In option (b) pentaamminehydroxochromium ( I I I ) c h l o r i d e , chromium metal makes bond with five ammonia molecule and one O H − molecule. Therefore, the coordination number for the metal in pentaamminehydroxochromium ( I I I ) c h l o r i d e is 6 . Hence the correct option for the metal with coordination 4 is option b. Reasons for incorrect options: In option (a) lithium tetrachlorocobaltate ( I I ) , cobalt metal makes bond with four chloride molecule. Therefore, the coordination number for the metal in lithium tetrachlorocobaltate ( I I ) is 4

Coordination Chemistry

It is a part of chemistry, in which the study of compounds that have central atoms surrounded by molecules or ions, known as ligand, is known as coordination chemistry.

Question

Chapter 22.3, Problem 4RC

Interpretation Introduction

Interpretation: The metal with coordination 4 is to be determined from the given option.

Concept introduction:

Coordination compounds: The compounds having coordination covalent bonds which form when metal ions react with polar molecules or anions.

Monodentate ligand is ligands which donate only one pair of electrons to form bond with metal. It only makes one bond with metal. Polydentate ligand forms two or more coordination bond with metal ions to form a complex.

Coordination number: The total number of ligands that forms bond with the metal atom.
