Chapter 22, Problem 22.28QP

Interpretation Introduction

Interpretation:

The tetrahedral complex from the following have to be determined –

1. (a) $\left[Zn{\left(N{H}_3\right)}_{2}C{l}_2\right]$ (b) $\left[Co{\left(N{H}_3\right)}_{3}C{l}_3\right]$ (c) ${\left[Co{\left(N{H}_3\right)}_6\right]}^{2+}$

(d) $\left[Ni{\left(H_{2}O\right)}_6\right]S{O}_4$ (e)  ${\left[Co{\left(en\right)}_2\left(H_{2}O\right)Cl\right]}^{2+}$

Concept Introduction:

• Complex compounds are primarily formed by transition elements which are d-block elements.  A co-ordination compound is known as a complex compound is made of metal atom/ion and ligand(s).  Ligands are considered as Lewis bases and the central metal atom is Lewis acid.  Ligands donate a pair of electron to metal ion and establishes bonding with metal ion which is known as co-ordinate bond and hence these compounds are named as co-ordination compounds.  The ligands represented inside the square brackets.
• Complex compounds exist in following geometries - tetrahedral, square planar, octahedral, etc.
