Chapter 19, Problem 53QAP

Interpretation Introduction

(a)

Interpretation:

The simplest formula of the compounds is to be written.

Concept introduction:

The simplest molecular formula is also known as the empirical formula for any compound. It represents the simplest ratio of element present in a compound. The formula is written in the form of element symbol and its mole ratio in its subscript.

The molecular formula is obtained from empirical formula as:

$\begin{array}{l}$ Molecularformula={(Empiricalformula)}_n$where,\\ n=\frac{molecular\text{ formula mass}}{molecular\text{ formula mass}}\end{array}$

Interpretation Introduction

(b)

Interpretation:

The structural formula is to be drawn for the complex formed.

Concept introduction:

The geometry of any complex is the spatial arrangement of ligands around the central metal cation. The chemical and most of the physical properties of the complex depends on this geometrical arrangement only. The number of ligands attached to the metal cation shows its co-ordination number.
